Three years ago, I received an email that changed how I thought about our business. A swimwear brand founder in California asked if we could manufacture period swimwear—swimwear designed to be worn during menstruation without additional protection. She had been getting dozens of messages from women asking if such products existed.
Today, period swimwear is one of the fastest-growing segments in the intimate apparel industry. More brands are recognizing that millions of women avoid swimming during their periods, often missing out on beach vacations, pool parties, water sports, and swimming classes. Period swimwear OEM services exist to solve this problem.
At Ljvogues, we've become specialists in period swimwear manufacturing, working with brands ranging from boutique startups to established retailers. In this guide, I'll share what we've learned about sourcing period swimwear OEM services—what brands need to know before they start, what to look for in a manufacturer, and how to bring your period swimwear line to market successfully.
Whether you're an established brand looking to expand your product range or a startup developing your first collection, this guide will help you navigate the period swimwear OEM process.
Before discussing OEM sourcing, let's clarify what period swimwear actually is. Unlike regular swimwear with some absorbency, period swimwear is specifically engineered to contain menstrual fluid while worn in water.
Period swimwear incorporates the same multi-layer technology found in period underwear:
Moisture-wicking inner layer: Pulls fluid away from the skin
Absorbent core: Contains the menstrual flow (typically 10-30ml capacity)
Waterproof barrier: Prevents leakage through the garment
However, period swimwear faces unique challenges that period underwear doesn't:
Water exposure: Must perform when submerged and when exiting water
Chlorine resistance: Should maintain integrity in pool environments
UV exposure: Needs sun protection without degrading materials
Secure fit: Must stay in place during swimming movements
This combination of requirements makes period swimwear more complex to manufacture than standard menstrual swimwear, which is why finding an experienced period swimwear OEM partner is essential.
The global period swimwear market is projected to grow significantly over the coming years. Key drivers include:
Increased menstrual health awareness: More women are comfortable discussing menstruation openly
Active lifestyle trends: Women participating in water sports, swimming classes, and beach activities
Sustainable product preferences: Reusable period swimwear replaces single-use tampons and pads
Body-positive movements: Brands embracing all women's needs, including during menstruation
For brands, entering this market now means establishing presence before the segment becomes saturated.
Building period swimwear in-house requires significant investment in equipment, materials sourcing, and specialized knowledge. Most brands—particularly startups and growing companies—benefit from partnering with an established period swimwear OEM.
Setting up production for period swimwear requires:
Specialized sewing equipment for waterproof seams
Multi-layer construction capabilities
Quality testing equipment for absorbency verification
Skilled workforce trained in period product manufacturing
The capital investment for in-house production typically exceeds $200,000 before producing a single unit. An OEM partner has already made these investments, spreading costs across hundreds of brands.
At Ljvogues, we offer 72-hour sample development for period swimwear. This means brands can receive physical prototypes within days of design approval, compared to months required to set up production facilities.
For brands competing in fast-moving markets, speed matters. An established period swimwear OEM can help you launch products in weeks rather than months.
Experienced OEM manufacturers have refined their processes over years and countless production runs. At Ljvogues, we've produced over 500,000 units of period swimwear, learning and improving with each order.
This experience translates to:
Consistent quality across all units
Optimized construction methods
Access to proven material combinations
Built-in quality checkpoints
When you work with a reputable period swimwear OEM, you're benefiting from their accumulated expertise and process improvements.
Now that you understand why OEM sourcing makes sense, let's examine what to consider when evaluating potential partners. When sourcing period swimwear OEM services, finding a qualified menstrual swimwear manufacturer requires careful evaluation of several factors.
Not all garment manufacturers can produce period swimwear effectively. Look for partners with specific experience in:
Period product manufacturing (not just swimwear)
Multi-layer construction techniques
Waterproof seam technology
Material science for absorbent fabrics
At Ljvogues, we've specialized in period products since 2016, with dedicated production lines for period swimwear. This specialization matters because the construction requirements differ significantly from standard swimwear.
Ask potential OEM partners:
How long have you manufactured period swimwear?
Can you provide samples of your period swimwear work?
What's your rejection rate for period swimwear production?
Do you manufacture period underwear as well?
Your brand reputation depends on the products you sell. Ensure your period swimwear OEM maintains relevant certifications:
Fabric Safety Certifications
OEKO-TEX Standard 100: Ensures fabrics contain no harmful substances
REACH compliance: European chemical safety regulation
FDA registration: Required for US market sales
Social Compliance
BSCI (Business Social Compliance Initiative): Labor and social standards
SEDEX: Supply chain ethical data exchange
WRAP (Worldwide Responsible Accredited Production): Factory compliance
Material Certifications
PFAS-free verification: Ensuring no "forever chemicals" in waterproof layers
GOTS certification: For organic cotton options
GRS (Global Recycled Standard): For recycled material claims
Ljvogues maintains all these certifications and provides documentation for brands requiring compliance verification.
The fabric's upstream factories provide OEKO certification for dyeing.
MOQ requirements vary significantly among period swimwear OEM manufacturers. Understanding your needs helps you find the right partner:
Business Stage | Typical MOQ Needs | Ljvogues Capability |
Startup/Testing | 30-50 pieces | 50 pieces minimum |
Growth Phase | 100-300 pieces | Flexible scaling |
Established Brand | 500+ pieces | Volume pricing |
At Ljvogues, we offer 50-piece minimum orders for period swimwear, recognizing that brands need to test products before committing to large production runs. This low barrier to entry allows startups and emerging brands to validate designs without significant inventory risk.
Before committing to bulk orders, you need to see and test your product. Evaluate the OEM's sample process:
Timeline
Sample development: How quickly can they produce prototypes?
Sample revisions: What's included in the sample fee?
Approval process: What's the workflow for design approval?
Ljvogues offers 72-hour sample development for standard designs, with extended timelines for highly customized products. This rapid turnaround helps brands move quickly from concept to market-ready product.
Sample Costs
Sample fees typically range from $50-200 per design
Sample costs are usually credited toward bulk orders
Multiple revisions may incur additional fees
Customization Scope
Can they produce your exact design specifications?
What customization options do they offer?
How flexible are they with design changes?
Understanding an OEM's production capacity ensures they can meet your needs. When selecting a period swimwear OEM manufacturer, production capacity is often a deciding factor for brands with urgent timelines.
Capacity Indicators
Daily/weekly production volume
Number of production lines dedicated to period products
Equipment capabilities
Workforce size and specialization
Lead Times
Sample production: 3-7 days typically
Bulk production: 3-6 weeks depending on order size

Material selection significantly impacts product performance and brand positioning. Here's what brands need to know:
The absorbent core determines how much fluid the swimwear can contain:
Organic Cotton
Natural, sustainable option
Good absorbency (20-25x its weight)
Softer feel against skin
Takes longer to dry
Bamboo Fiber
Natural antibacterial properties
Excellent moisture-wicking
Soft and comfortable
Premium positioning
Microfiber Blends
Highest absorption efficiency
Fastest drying time
Most durable through wash cycles
Often more affordable
Modal/Tencel
Sustainable wood-pulp base
Luxury hand feel
Good moisture management
Premium price point
Period swimwear outer layers must balance durability, comfort, and performance:
Swim Fabric Options
Nylon/spandex blends: Most common, excellent stretch and recovery
Polyester blends: Better chlorine resistance
Recycled nylon: Sustainable option (ECONYL, etc.)
Recycled polyester: Eco-friendly alternative
Chlorine Resistance
For pool use, chlorine-resistant materials extend product lifespan. Standard swimwear lasts 6-12 months with regular pool use; chlorine-resistant options can last 2-3 years. Our chlorine-resistant period swimwear options are tested for durability.
The waterproof layer prevents leakage while allowing breathability:
PUL (Polyurethane Laminate)
Traditional waterproof material
Thin and flexible
Durable through washing
Widely used in period products
TPU (Thermoplastic Polyurethane)
Alternative to PUL
Slightly different feel properties
Equally effective waterproofing
Often used in performance wear
The waterproof layer prevents leakage while also being breathable.
Many consumers actively avoid PFAS "forever chemicals" in their products. Reputable period swimwear OEM manufacturers should offer PFAS-free options. At Ljvogues, all our period swimwear is PFAS-free certified, allowing brands to make this claim confidently.
When developing period swimwear for OEM production, consider these design factors:
Period swimwear requires more fabric coverage than regular swimwear to accommodate absorbent layers:
Higher waistbands provide better leak protection
Full-coverage bottoms work better than thong styles
One-piece designs offer more secure protection
boyshort and skirt styles balance coverage with aesthetics
When working with a period swimwear OEM like Ljvogues, we recommend discussing coverage options early in the design phase to ensure the final product meets your customers' protection expectations.
Strategic seam placement affects both comfort and leak protection:
Flatlock seams reduce chafing during water activities
Gusset construction should align with absorbent core
Avoid seams directly over high-flow areas
Bonded seams provide better waterproofing than stitched
LJVogues workers sew menstrual swimwear
Absorbent layers add bulk, affecting how period swimwear fits:
May need to size up for comfort
Stretch materials accommodate the added volume
Consider sizing charts that account for absorbent layer
Fit testing with real wearers essential
Period swimwear doesn't have to look medical or bulky. Modern designs can be:
Fashion-forward with current trends
Available in various colors and patterns
Styled like regular swimwear
Discreet with no visible differences from standard swimwear
Swim Skirt Shorts Built-In
Working with a period swimwear OEM involves several phases:
Discuss your brand, target market, and product requirements
Review material options and their implications
Receive guidance on design feasibility
Establish pricing and timeline expectations
At Ljvogues, we begin every partnership with a consultation to understand your vision and constraints. This helps us recommend the most suitable approach.
Finalize design specifications
Select materials and colors
Produce initial samples (typically 3-7 days)
Test samples and request revisions as needed
Sample development typically involves 2-3 iterations before final approval. Budget 2-4 weeks for this phase.
Confirm order quantities
Finalize pricing and payment terms
Establish production schedule
Arrange material procurement
Fabric cutting and preparation
Multi-layer construction
Quality inspection at each stage
Final testing and QC check
Standard production takes 2-3 weeks for most order sizes, with larger orders requiring additional time.
Custom packaging options (brand box, swing tags, etc.)
Quality verification before shipping
Arrange shipping logistics
Provide tracking information
Understanding cost drivers helps you budget appropriately:
Cost Factor | Impact |
Materials | 35-45% of cost |
Labor | 25-35% of cost |
Overhead | 15-20% of cost |
Profit margin | 10-15% |
Order quantity: Higher volumes reduce per-unit cost
Material selection: Organic/specialty fabrics increase costs
Design complexity: More intricate designs require more labor
Certification requirements: Additional certifications add costs
Packaging: Custom packaging increases per-unit price
Period swimwear OEM pricing varies based on these factors:
Budget options: $8-15 per unit
Mid-range: $15-25 per unit
Premium: $25-40+ per unit
These prices typically include basic packaging. Custom packaging, labels, and hang tags add $1-5 per unit depending on specifications.
Through our work with dozens of brands, we've seen common pitfalls:
Some brands rush samples into bulk production without adequate testing. Always test samples through multiple:
Wear tests during actual periods
Swimming activities (pool and ocean)
Washing cycles
Various activity levels
Not all period swimwear handles chlorine well. If your product targets pool swimmers, ensure the OEM uses chlorine-resistant materials and communicates this clearly.
Some brands expect startup-level MOQs from factories designed for larger orders. Align your expectations with the OEM's business model from the start.
Never assume an OEM has certifications—verify them. Request copies of certificates and check expiration dates.
Rushing production often leads to quality issues. Build adequate time into your launch timeline.
