I would default to whatever Doge's kid rides.

Many of the "fast" skin suits, such as Castelli, are not very durable - big depends. So be prepared to have seams rip that require repair with a special sewing machine or they are good for a couple of races. My wife, who set a UCI world record this year on the track, rode in a Champion carbon skin suit with the zipper on the back. If fit really well and seems durable. Most clothing manufacturers do not understand that women are not small men.

Whatever you get, the fit should be amazingly tight and hence, the likelihood to damage it when putting it on and taking it off.
