Underwire and thick straps are non-negotiable

Yes, you need support — underwire and wide adjustable straps make the difference.

Most “one-size-fits-most” bikini tops are designed for B cups at best. If you’re a D or above, triangle tops and bandeaus will leave you holding everything together instead of enjoying the water. Not worth it.

Look for swim tops that come in bra sizes, not S/M/L. Brands like Panache, Freya, and Bravissimo actually engineer the cups and underwire to hold weight. Halter tops seem like a good idea but they’ll wreck your neck after an hour. Wide straps or racerbacks distribute the load better.

You don’t have to spend a fortune — Target’s Shade & Shore line has surprisingly solid underwire tops in D+ sizes for under $30. Just make sure the band fits snugly and the straps adjust.

Your neck will thank you.
