Bright red and gingham are the swimsuit trends for summer 2025.

Yes, those are the two big ones, plus a few others worth knowing.

Red is having a moment — not fire truck, but a rich tomato red. It’s been all over runways and street style. Gingham is back too, but not in a picnic-tablecloth way. Think 90s baby-doll meets French girl.

Tie-dye is still hanging around, but it’s more muted and earthy now. Also keep an eye on butter yellow and deep chocolate brown. Patterns are leaning toward all-over prints or bold single colors. Micro prints?
