There used to be a one-piece lycra suit (nice! ) made by Alpha Marine in the UK. I certainly had two or three of them and so did just about everyone racing seriously on the Tornado circuit in the early '80's. They were light blue with a white arm and leg stripe each side. We wore them over all our gear as the last thing we put on supposedly to cut down wind resistance and stop us getting hung up on lines, wires etc. around the boat. If you were a crew, you cut a button hole and stiched round it for your trapeze hook to poke through. They worked really well but we all looked ridiculous .

Doesn't anyone make anything similar today?
