Accessories sell the retro look.

Yes, high-waisted bottoms are the foundation, but they’re not enough on their own. The real retro vibe comes from the rest of the outfit.

Throw on cat-eye sunglasses and a wide-brim straw hat. Tie a sarong or a button-up cover-up (unbuttoned) over the top. Flat sandals or espadrilles work better than flip flops. Hair in victory rolls or a bandana. And a red lip, obviously.

Skip the sporty sunglasses and neon nails. Lean into the 1950s beach-goddess energy — it’s more about the attitude than the bikini itself.

If you do it right, you’ll look like you just stepped off a movie set, not a hotel pool.
