FleshForge's Peligro Swimsuit is quite unique in its design. I don't recall coming across a similar design from freebies or the regular Daz store. May be inspired by Brasilian style.
The swimsuit is simmed and has been tested on female characters with normal hips. For slimmer models such as the one represented in the preview, you may have to disable simming or rework the sim file.
