What's the name of a jumpsuit that looks like a swimsuit but doesn't look like a thong?

There are T-shaped swimsuits (Taobao is rare), T-shaped customer service (T-shaped crotch is very wide), T-shaped sexy clothes (ice silk, mesh cloth and so on), T-shaped body shaping clothes and bottoming clothes (women wear them every day, and their crotch is generally buttoned). I don't know which one you are describing ~ ~ ~ ~.
