Try WearMoi tights. It used to be that these were only available in the UK (ordering from their website meant an overseas delivery and dealing with foreign exchange rates), but now they can be gotten from a retailer in San Francisco, Aurora's Collection. I don't know the URL for it, but you can search for it on the 'Net.
Another alternative is MaleSkin (www.maleskin.com). Their tights come in all kinds of fabrics, including velvet, for you Renaissance types out there.[/i]
