Product Description

These side tie period swim bottoms are designed as standalone separates — sold without a matching top, intended to be mixed and matched with existing bikini or tankini tops. This positioning creates a cross-selling opportunity for brands: customers can pair the leak-proof bottoms with swimwear they already own.

The functional double side ties provide adjustable tightness, allowing users to customize the fit for maximum security during active swimming and wave riding. This adjustability also reduces sizing returns — a significant operational benefit for retail brands.

The 80% nylon + 20% spandex dual-layer outer shell provides excellent stretch, rapid drying, and UPF50+ sun protection — the only Ljvogues swimwear model with a UV protection rating. The full-coverage silhouette enhances modesty and security, making this model popular among teens experiencing their first periods, active women, and postpartum mothers.

The proprietary gusset uses a hydrophobic (water-repelling) outer membrane that prevents pool and ocean water from entering, combined with hydrophilic (water-absorbing) inner layers that trap menstrual fluid securely. This prevents the waterlogging effect typical of regular sanitary pads.

Every batch undergoes testing for stretch recovery, chlorine colorfastness, saltwater colorfastness, and leakproof integrity — the most comprehensive testing protocol of any Ljvogues swimwear model.

For private-label buyers, OEM/ODM customization includes heat-pressed logos, custom-dyed fabrics with Pantone matching, digital and sublimation printing (floral, geometric, tropical patterns), and custom retail packaging.

Key Specifications

Leakproof Gusset Technology

Design Features

Functional Double Side Ties

The side strings are fully functional — not decorative. Users tighten or loosen to achieve a customized fit, keeping the swimwear firmly in place during active swimming and wave riding. This adjustability reduces sizing returns for retail brands.

UPF50+ Sun Protection

The outer shell provides UPF50+ UV protection, shielding sensitive skin from harmful rays. This is the only Ljvogues swimwear model with a stated UPF rating.

Full Coverage Silhouette

Intentionally designed for full coverage — enhanced modesty, security, and prevention of accidental exposure. Popular among teens, postpartum mothers, and women who prefer more coverage than bikini bottoms provide.

Quick-Drying Dual-Layer Shell

The 80% nylon + 20% spandex dual-layer blend provides excellent stretch recovery and rapid drying times — practical for repeated use between swims.

Mix-and-Match Separates

Designed to be sold without a matching top. Customers pair with existing swimwear, creating cross-selling opportunities and reducing the need for full-set inventory.

Frequently Asked Questions

How does the leakproof core work in the water?

The core uses a hydrophobic (water-repelling) outer membrane that stops external water from entering, combined with hydrophilic (water-absorbing) inner layers that trap menstrual fluid. This prevents the gusset from becoming waterlogged.

Are the side ties functional or just decorative?

Fully functional and adjustable. Users tighten or loosen the strings for a customized fit. This significantly reduces sizing returns because one size can accommodate a range of body measurements.

Can we request custom prints instead of solid black?

Yes. Black is the staple color. Custom digital and sublimation printing available — supply floral, geometric, tropical, or custom patterns for the outer shell.

Are the materials PFAS-free?

Yes. All leakproof membranes and textile treatments are 100% PFAS-free, verified through third-party testing. Safe for the wearer and the environment.

What is the MOQ and lead time?

"Flexible MOQ" is stated but no specific number is provided. Rapid prototype development is offered. Contact the Ljvogues team for MOQ, pricing, and timeline.
