Yes, but only if you buy the right one.

A cheap, thin white swimsuit will go translucent the second it hits water. If you want it to stay opaque, look for double-lined fabric (check the tag) and a thick nylon-spandex blend. Avoid anything that feels like a flimsy cotton T-shirt or a cheap stretch knit.

Pure white is actually easier than off-white or cream, because those warm tones sometimes show more contrast against skin. Go for a matte finish, not shiny. Shiny fabrics magnify translucency.

If you’re between sizes, size down — less fabric slack means less bunching and less transparency.

Stick with lined, matte, high-density fabric and you won’t have to worry.
