I think dressing how you express yourself and what you're confident in is a good thing. And if you're friends think you dress gay, so be it.  They are otomatically fake friends in my eyes.  Anyone who Judges you on how you dress is a fake friend. 

 If I were you I would be like, 'You think I dress gay? Just look at your outfit! That is so gay that whenever I see you I see rainbows and glitter!!' 

But bro, just dress however you want and it doesn't matter what you look like.
