Is this a girls top he is wearing?

It's just a black tank top. Usually he buys either men' couture, or unisex. As for buying some women's items, I don't think he really cares. He wears what he wants regardless of what others tell him. He's always been like that, and no I don't think that makes him gay. It makes him unique; it makes him an individual with his own sense of style. He can pull it off too.
