US Patent 12121093 Swimsuit

A swimsuit formed from a stretchable fabric that is configured to cover at least the buttocks and the abdomen in use, including: a first tightening portion configured to cover the entire abdomen and extend to the upper back; and a pair of symmetric first reinforcing bands each configured to extend from one side of an armhole of the swimsuit across the abdomen and down to an end portion of the swimsuit on the other side, the pair of first reinforcing bands intersecting with each other in an area of the swimsuit covering the abdomen. A swimsuit having this configuration can support the wearer's flat posture while preventing the abdomen from sinking during swimming.
