A swim bra top that does not go transparent when it gets wet and does not sag afterwards, which is where most sports bras fail the moment you take them near the ocean.

What to look for in one

Moisture-wicking fabric, flat-lock seams that lie flush instead of grating, and enough compression to support without restricting your breathing. Removable pads so you can decide. If you notice you are wearing it, something is wrong with it.

Wear it under or on its own

Under a rash guard for a full session, or on its own with swim leggings for a workout or a beach day. Same top either way.
