Doesn't matter at all and shouldn't matter. Artists are artists; they express themselves in whatever ways they feel are appropriate, whether it be wearing strange choices of clothing or painting their faces or whatever. Look at David Bowie, Freddie Mercury, Lady Gaga and on the opposite end of the spectrum, look at Young M.A. If the music is good then nobody should really care at all how they look or present themselves. Music and fashion are entirely subjective, what's dope to one person may be dog sh*t to the next. People getting up in arms over what Uzi wears are just silly and I feel like they're likely somewhat insecure.
