All these tights with skirts sound so inconvenient!!! I drink a fair amount of water during practice, so bathroom issues would dissuade me from wearing any body tights! Even during tests or exhibitions that I have done, I manage to need to go to the bathroom and have to peel off all those layers in a cold bathroom.
Plus, sometimes I put in (or take out) a tailbone pad during the practice time, so the ability to do that rinkside is really worth it to me!
I like to practice in compression tights (a lot of runners and skiers wear those). On top of those I wear Chloe Noel over the boot leggings. Compression tights give me a great feeling of security. They are also great for any thigh jiggle:-)
Chloe Noel, while expensive, are the best ones I have worn! I always wash mine in a washing machine and dry them in the dryer (even though the manufacturer says to hand wash them--- ridiculous for sports wear!!). But again, I personally do not like skirts for practice.
