Treat your rash guard like a regular t‑shirt.

Just pair it with board shorts, swim trunks, or even casual linen shorts. It’s already a sporty piece, so don’t overthink it. Leave it untucked, roll the sleeves once if they’re long, and wear it with flip‑flops or slip‑on sandals.

If you want a little more style, go for a rash guard in a solid color (navy, black, white) or a subtle print – nothing loud. It works as a cover‑up over a bikini too, especially unzipped. That’s really it.

Don’t try to dress it up with jeans or chinos. That looks like you forgot to change after surfing. Keep it beach‑casual.

You’ll look fine as long as you don’t tuck it in.
