Wild Tights
There is a reason everyone wears tights ... we all look better in them. They make everyone's legs look good. The sizing is the same as the American Cut shorts but with longer fabric that goes all the way to your ankles. Will these work for a guy who is 6' 5"? Yes. The spandex really stretches in every direction and with two long legs of spandex fabric, the tights stretch downwards and down and down. No, they don't look like capri pants.
Unisex fit. Men and women both look good.
Up to you if you want to go commando or wear something underneath. If you are commando in your rowing trou, why shouldn't you be in your tights? Makes sense, right? :)
Look for the Fabric 411 tab to check the Commando Transparency Index.
