High-neck compression tops are your best bet.

Yes. Look for a high-neck or full-coverage swim top with compression fabric and sturdy underwire.

High-neck styles cut across the bust visually, so they don’t emphasize width the way a scoop neck or triangle top does. The compression fabric flattens and smooths, while underwire or molded cups keep everything in place without adding bulk. Thick straps are key—thin halter straps will dig in and hurt after an hour.

Skip anything with ruffles, horizontal seams, or padding you can remove (you always remove it). Also avoid traditional halter tops—they pull up and center, which makes your bust look bigger. A tankini with a shelf bra or a one-piece with power mesh lining works great too.

If you can, try on a few brands in a store. Bodyshaping swimwear from Land’s End, Athleta, or even Target’s Shapermint line are solid picks. Don’t trust Amazon reviews alone—the fabric quality varies wildly.

You want streamlined, not squished. The right top will feel secure without needing constant tugging.
