Everyone, of course, is free to do as they choose. But I have to keep it real here...
I believe there are very few parts of the USA where (other than a scottish kilt situation) a male won't be looked upon as a freak if he's wearing a skirt. If you're ok with that, I say go for it. It all depends on the individual and how they handle their interaction with society. Sorry, but I don't believe it will ever be the norm for males to wear skirts in public.
