Femilet Swimwear

For underwired bikini tops, start with your normal UK bra size. The band should sit level and secure around the body, and the cup should contain the breast without the wire sitting on breast tissue or the upper edge cutting in.

A full-coverage underwired top is the best starting point for fuller or projected busts. A moulded wireless top creates a smoother, softer shape and may feel less rigid, but it should still anchor securely under the bust.

For bikini bottoms, begin with your usual dress size and choose coverage by preference. Full or high-waisted briefs give more coverage; classic briefs sit lower and feel lighter.

For one-piece swimsuits and tankinis, check the torso as well as the bust. Shoulder pulling or a neckline dragged downward can be caused by a body-length mismatch rather than a cup-size problem.

• Choose an underwired full-coverage bikini top for the strongest bust support.
• Choose a moulded wireless bikini top for a softer feel and smooth rounded cup.
• Choose a tankini when you want the flexibility of separates with more torso coverage.
• Choose a one-piece for simple all-over coverage; check torso length as carefully as bust fit.
• Choose a full or high-waist brief for more coverage, or a classic brief for a lower line.

Femilet swimwear uses stretch swim fabrics based largely on polyamide and elastane, with different linings and moulded-cup materials according to style. This gives the fabric recovery, a smooth hand and enough elasticity for movement in water.

Chlorine, salt, sunscreen and prolonged heat all degrade stretch fibres, so prompt rinsing and gentle washing make a meaningful difference to how long the garment holds its shape.

• Rinse in cool fresh water after every swim.
• Wash gently according to the care label; hand washing is the safest default.
• Avoid bleach, fabric conditioner and aggressive stain treatments.
• Do not wring moulded cups or twist underwired tops.
• Dry naturally in shade and avoid tumble dryers, radiators and prolonged direct heat.
• Do not leave damp swimwear rolled inside a towel or bag.

For gentle hand washing, Soak lingerie wash is a convenient option for washable swimwear, subject to the individual care label.
