You need a long torso specific suit.

Yes. If you’ve ever had a one-piece ride up or dig into your shoulders, it’s not your body—it’s the suit. Standard fits assume a shorter torso, so you end up with wedgies and pressure points.

Lands’ End is the gold standard here. They make “long torso” versions of most of their one-pieces, and they actually fit. Aerie has a solid long torso line too, usually at a lower price. SwimsuitsForAll is another option if you want more variety.

Avoid “tall” sizing from brands that don’t specialize in swim—it’s often just a longer inseam on bottoms, not a longer torso. You want a suit built for length, not scaled up.

Your torso is not the problem; the suit is.
