A Manufacturing Roadmap for Brand Founders & Amazon Sellers: Leak-proof technology, OEM vs. ODM strategies, and navigating MOQs in a booming niche.
The functional apparel market is witnessing a revolution. Just as period panties disrupted the underwear industry, Period Swimwear is rapidly becoming a standard category for major retailers and specialized boutiques.
According to 2025 market analysis, this sector is projected to grow by 18.5% annually. Consumers—from Gen Z teens to eco-conscious adults—are demanding sustainable, reusable alternatives to tampons, even at the beach.
For brand owners, this represents a massive opportunity. But launching a swimwear line requires more than just a good design; it requires hydro-engineering. A period swimsuit cannot simply be a waterproof panty; it must withstand chlorine, salt, and movement without swelling.
In this guide, I will walk you through the step-by-step process of turning your concept into a best-selling product, leveraging our decade of expertise as a leading OEM/ODM manufacturer.
Before contacting a factory, you need to narrow down your target. "Period swimwear" is too broad. Based on our production data at Ljvogues, the most successful startups focus on specific sub-niches:
The "Teen & First Period" Market:
Focus: Modest cuts, bright colors, and high security for school swimming lessons.
Why: Parents are the biggest spenders here, prioritizing anxiety reduction for their daughters.
The "Competitive Sport" Market:
Focus: High-performance, chlorine-resistant fabrics (like PBT blends) for athletes who can't skip training.
Why: Functionality trumps fashion; margins are higher.
The "Eco-Conscious" Market:
Focus: Recycled Nylon (ECONYL® equivalents) and plastic-free packaging.
Why: Aligns with the "Blue Beauty" movement protecting oceans.
CEO Tip: When you define your audience clearly, it helps manufacturers like us recommend the right material blends. For teens, we prioritize security (wider gussets). For athletes, we prioritize drag reduction.
The difference between a regular swimsuit and a period swimsuit lies in the Gusset Engineering. If you are selling these products, you must understand the physics to explain it to your customers.
At Ljvogues, we use a specialized 4-Layer Hydro-Tech Stack:
The Interface (Inner Layer):
Function: Moisture-wicking and anti-bacterial mesh.
Key Spec: Must dry quickly to prevent skin irritation.
The "Non-Swelling" Core:
Function: Holds the fluid.
Crucial Distinction: Unlike period panties, this layer must be compressed and thin. Standard cotton cores swell when wet, creating a "diaper" effect. We use dense, hydrophobic-treated absorbents that only trap blood, not pool water.
The Hydro-Barrier:
Function: A waterproof but breathable TPU membrane. It keeps pool water out and menstrual fluid in.
The Shell Fabric (Outer):
Function: Treated with DWR (Durable Water Repellent) to ensure the suit sheds water and dries fast.
Compliance Note: Always ask for PFAS-free certifications. US and EU markets are banning "forever chemicals" in water-resistant textiles. We provide UL/SGS reports for all our swimwear materials.
When sourcing from Ljvogues, you have two pathways. Choosing the right one depends on your timeline and budget:
Feature | Option A: ODM (White Label) | Option B: OEM (Custom Build) |
Best For | Startups, Amazon Sellers, Influencers | Established Brands, Designers |
Process | Choose from our catalog → Add Logo | Provide Tech Pack → Build from scratch |
Lead Time | Fast (15-30 days) | Standard (45-60 days) |
MOQ | Low (Start at 100 pcs) | Medium (Start at 1,000 pcs) |
Pros | Proven fit, fast launch, low risk | Total exclusivity, unique design |
One of the biggest hurdles for new brands is the MOQ. Here is how to hack it:
The "Stock Fabric" Strategy: Custom dyeing requires high volumes. To keep MOQs low (e.g., 50-100 pieces), we recommend launching with Stock Colors (Black, Navy, or our seasonal prints).
The "Mix & Match" Strategy: Use the same black fabric across 3 different styles (Bikini, One-Piece, High-Waist). This aggregates your volume and lowers your unit cost.
The "Print" Strategy: Digital sublimation printing (for patterns) has lower MOQs than solid dyeing. Use this to your advantage to create unique looks without massive investment.
A return rate due to leakage can kill an Amazon listing instantly. To ensure you are buying high-quality period swimwear, ask your supplier these critical questions:
"Do you use bonded seams?"
Why: Heat-bonded or silicone-taped seams prevent water from wicking inside the stitching holes.
"What is the gusset width?"
Why: Swimwear moves. We recommend a slightly wider gusset (7-8cm) for swimwear compared to underwear to prevent side leaks during swimming kicks.
"Can I see the Chlorine Resistance Report?"
Why: Standard Spandex breaks down in chlorinated pools. We use high-grade Creora® Highclo™ or equivalent fibers for longevity.
Q: Can you swim in period swimwear without a tampon?
A: Yes. High-quality period swimwear (like Ljvogues') is designed to absorb light to medium flow (equivalent to 1-2 tampons) on its own. For heavy flow days, it is often used as a backup to a menstrual cup.
Q: What is the lead time for custom swimwear?
A: For ODM (White Label), it takes about 3-4 weeks. For OEM (Custom Design), expect 6-8 weeks including sample approval and material sourcing.
Q: Is your swimwear PFAS-free?
A: Yes. Ljvogues provides certified PFAS-free options that comply with the latest US (California/New York) and EU regulations.
The period swimwear market is open for innovation. Whether you are an Amazon seller looking for the next winning product or a boutique owner expanding your inventory, the key to success is a product that women can trust underwater.
At Ljvogues, we specialize in helping brands scale. From low-MOQ white label solutions to complex custom OEM manufacturing, we provide the leak-proof technology you need to succeed.
