Our take on the Cupshe Onyx Bralette & Lingerie Set

The Cupshe Onyx is a one-piece swimsuit with a single asymmetric shoulder strap and a solid black finish. It is cut as a bralette-style top with tummy-control lining through the midsection, which smooths the waist without the compression of a full shaping suit. It suits women who want a sleek, covered one-piece for the beach or pool and prefer a clean look over cutouts and prints. Against other tummy-control one-pieces, it stands out for the one-shoulder neckline, though that strap means less adjustability than a standard two-strap suit.

Questions and answers

Does the one-shoulder strap adjust?
No. The suit has a fixed one-shoulder strap, so fit depends on the size you choose rather than on tightening a strap.
How does the tummy control feel?
The lining is designed to smooth the waist and midsection. It adds light compression, so expect a snugger feel through the middle than an unlined suit.
Is this a swimsuit or lingerie?
It is a one-piece swimsuit for swimming and beachwear, despite the bralette-style top.
What sizes does it come in?
It is sized in standard alpha sizes for women. Check the waist measurement against your own before choosing.
Can teens wear it?
Yes. It is listed for teens and adults, and the full one-piece coverage suits younger swimmers.
How should I care for it?
Rinse in cold water after each swim and dry flat in shade. Avoid wringing, which can stretch the tummy-control lining.
