Most swimsuits promise support. Jace delivers it.

A high neckline that actually holds you in place, signature ruching that sculpts through the waist, and an open back with zipper closure that keeps everything exactly where it should be. Built for the woman who wants real support through the bust without giving up comfort anywhere else — structured where it counts, soft everywhere it should be.

Moderate back coverage means you can move, sit, swim, and live without thinking twice. The kind of suit you put on with confidence and never have to reconsider.

In the water, out to lunch, onto the next trip. Wear it everywhere. The cost per wear does the math for you.


FIT AT A GLANCE

  • High neckline for a secure, supportive feel
  • Open back with zipper closure — a clean, intentional detail
  • Signature waist ruching that shapes without feeling tight
  • Moderate back coverage for a confident, wearable fit
  • Slightly lower-cut leg than the thong version
  • Designed to wear as swim or styled as a bodysuit
  • Designed to fit snug through the waist and body
  • Size up if you're between sizes

NOT SURE WHICH JACE IS RIGHT FOR YOU?

Jace Moderate: High neckline, open back with zipper, moderate back coverage, slightly lower leg cut. Structured support with a secure, everyday finish.

Jace Thong: High neckline, open back with zipper, thong back, higher-cut leg. The same structure up top with a sleek, minimal finish.


THE FIT

Designed to fit snug through the waist and body. Size up if you're between sizes.

  • Ella is 5'11", Bust 37", Waist 30.5", Hips 41" and wears a size XL

FABRIC & FEEL

A nylon-spandex blend that moves with your body and recovers its shape every time. Buttery against the skin and built to last season after season — no replacing it every summer. The kind of suit you come back for in every color. And most of our customers do.


WEAR IT BEYOND SWIM

Jeans and a kitten heel for lunch. Tailored trousers for wherever the evening takes you. Jace goes wherever you do.


To keep your suit looking its best, we recommend hand washing your suit by itself with cold water and a gentle soap after each use. Do not soak, just a quick wash will do! Please be sure to dry in shade.

Do not pack wet suits with other garments.Try not to keep your suit balled up for extended periods of time—especially if it's still wet. 

Do not dry clean garments.Avoid contact with sunscreens, oils & high levels of chlorine- this may cause the color to fade and damage the material. Avoid rough surfaces (rocks, stone, pebble, pool surfaces). Please note that contact with rough surfaces may cause pilling or damage to the fabric, and we are unable to take responsibility for wear caused by these conditions.

Because our fabric is intentionally soft and delicate, extra care will help extend the life of your suit and keep it in beautiful condition wear after wear.
