Guide

Women's Swimwear

Swimsuits and bikinis need to stay put as you push off and reach forwards. Separately sold bikini pieces let you choose top and bottom independently; tankinis and swim shirts offer more coverage.

Key points

  • Choose top and bottom using the relevant body measurements for each.
  • Straps and necklines should stay in place while you swim.
  • A bikini top is often sold without matching bottoms.

Swimsuit or bikini?

  • Swimsuit (One piece)

    Straps and torso need to fit together. Torso length matters alongside circumference.

    • Advantage: No gap between top and bottom
    • Drawback: Less flexibility for different top and bottom sizes
  • Bikini top (Choose separately)

    A separately sold top can be paired with bikini bottoms chosen in their own size.

    • Advantage: Size independent of the bottoms
    • Drawback: Matching bottoms are an additional purchase

Common questions

Are both bikini pieces included?

Only if the listing explicitly describes a set. A bikini top or bikini bottom is a single piece. Buying separately lets you combine different sizes.

How can I spot a swimsuit that is too short?

The straps may pull hard on your shoulders or the leg opening may ride up when you stretch. Check torso length against the size chart; extra width alone may not solve it.

Is a rashguard a wetsuit?

No. A thin swim shirt covers skin but does not provide the insulation of a wetsuit. Extended time in cold water needs equipment designed for those conditions.

How do I care for swimwear after the pool?

Rinse with fresh water and dry according to the care label. Hard wringing and high heat can damage stretch fabric. Let it dry as fully as possible before packing.
