Product Description

Model 9020 is a one-piece period swimsuit with an open-back design and adjustable spaghetti straps — the only one-piece silhouette in the Ljvogues swimwear range. The backless cut delivers the aesthetic that drives consumer demand, while the front provides full, smooth coverage. From the outside, there is no indication that this is a period swimsuit.

The adjustable spaghetti straps sit comfortably on the shoulders, reducing pressure and allowing freedom of movement. The 4-layer leak-proof liner is integrated seamlessly into the gusset/crotch area, completely independent of the back design — the open-back cut enhances aesthetics without affecting protection.

The 85% nylon + 15% spandex outer shell is exceptionally soft, breathable, moisture-wicking, and skin-friendly — comfortable whether swimming laps or lounging poolside. The TPU waterproof membrane prevents pool and ocean water from entering the absorbent core, keeping the swimsuit lightweight when submerged.

For plus-size buyers, Model 9020 offers graduated liner coverage — the leak-proof gusset is adapted for extended sizes (up to 4XL+), ensuring protection remains effective across all body types. The in-house pattern grading team specializes in inclusive sizing.

For private-label buyers, Model 9020 is available from 300 pcs per design with full OEM/ODM customization including neckline modification, back cut depth, strap width, ruching, cut-outs, custom Pantone colors, sublimation prints, branded neck labels, custom care tags, and retail-ready packaging.

Frequently Asked Questions

Does the open-back design compromise the leak-proof function?

No. The 4-layer leak-proof liner is located exclusively in the gusset/crotch area and is completely independent of the back design. The backless cut enhances aesthetics without affecting protection.

Will the built-in liner absorb pool water and become heavy?

No. Layer 3 (TPU waterproof membrane) acts as a hydrophobic barrier, preventing external water from entering the absorbent core. The swimsuit remains lightweight and comfortable even when fully submerged.

Yes. The pattern grading team specializes in inclusive sizing. Sizes up to 4XL or beyond, with graduated liner coverage to ensure the leak-proof gusset remains effective on all body types.
