Haikyuu Characters and Fashion

Hinata-just wears whatever is convenient and won't burn someone's eyeballs off
Kageyama-one day he tried to wear eyeliner just for the heck of it and nearly lost his eye in the process. Many tears were shed that day.
Suga-trendy and spends 83817 hours picking out clothes so that he looks presentable
Daichi-wears casual clothing but nothing too bad
Tsukishima-"The only reason I even bother picking out clothes is so that people won't take pictures of me and make it a meme"
Yamaguchi-the only person that wears normal things
Nishinoya-wears things so ridiculous you can't even begin to imagine
Tanaka-will wear something similar to Noya BC bros
Asahi-will wear something more formal

"THAT PERFUME IS DETESTABLE HOW DARE YOU GO OUT ON A DATE WEARING XXX BRAND'S OCEAN-SCENTED PERFUME THIS IS HORRIBLE"
Iwaizumi-same as Hinata

Bokuto-wears tight stuff so that it makes him look buff so that Akaashi will notice him. Girls will notice him? Yeah so that girls will notice him
Akaashi-haahah I'm going to wear whatever I want

Kenma-shut-ins don't go out
Kuroo-spends reasonable amounts of time picking his clothes out but 72873 hours styling his hair
