I work in the sport; we have our own share of hotties who could make such a calendar. There are a couple who are under-18 though.
For me, even if these Belarusian ladies hadn't been half-naked, I would still have wanted to look at their pictures. There's something about a spectacularly beautiful woman that shines through even if she's wearing a potato sack. Naturally beautiful cheerleaders in a calendar will be a hit even if they are wearing their full regulation uniforms.
