Bal-Togs is the only company I know of that makes men's leotards.They're sold in many places, often not advertised as Bal-Togs.  Butthe classic Bal-Tog numbers (BT-380, BT-381, etc) indicate they reallyARE Bal-Togs.

You should decide the following: 1. Material: cotton or spandex? 2. Color: black or white, or sometimes navy blue. 3. Style: short sleeved or tank. 4. Style: thong or full-bottomed. I personally prefer white tank-top cotton, full-bottom.  ANYTHINGwith sleeves gets stinky VERY fast on men in ballet class.  Also, Idon't like the neckline on BT's short-sleeved leotards, I think it'stoo low.

Another brand we've used for professional costumes is Reflexions.  Ithink it's technically a "woman's" leotard, but the basic version sobasic that it can aparently serve either gender.  I like itsshort-sleeved neckline a LOT better than Bal-Tog's.

If you wear underwear and a leotard, I don't think a dance belt isnecessary.  Just make sure your underwear doesn't show (it won't ifyou use thick black men's tights).  But try it for yourself, and seeif you are satisfied with the level of support provided and theoverall look.  I personally don't like the feeling a thong dancebelt.

If your tights fall down, cut off the feet and roll them up as far asis required to prevent them from falling down (I roll them to justbelow my knee).  Wear socks or go bare-foot under your ballet shoes.Avoid heavy cotton socks, that looks dumb and you can't feel thefloor.  Try to get socks that approximate the thickness and materialof the tights they're replacing.  I use K-Mart white men's nylon dresssocks, which are just a LITTLE bit thinner than Capezio tights.Ultimately, socks are very convenient;: you can take them off and cutyour toenails, for example, without stripping.

Unitards give very little support, and require a dancebelt.
