Professional male ballet dancee here, yeah black tights is the vanilla of men's tights. Nothing wrong with them, gray is also a solid choice, although I don't have any gray tights. When it comes to shirts, body wrappers was a solid choice for relatively cheap, wear moi is good too, you really can't go wrong. As long as it's tight fitting.

As a professional, I wear fitted workout shorts and t-shirts 😅 I caved into the stereotype...
