This simple but impressive anime costume is for Danganronpa Byakuya Togami cosplay, which is composed of black suit, balck shirt and necktie, an easy cosplay idea for girls and boys. He has same name with the handsome bleach character Byakuya Kuchiki (he is one of my favorite captains). Hence, I remembered his name at the first time I know this Dangan Ronpa boy.
As for Byakuya Togami, we could tell something from this black suit, and he has the title of Ultimate Afflent Progeny, hence he is an arrogant and cold guy (he looks somewhat cool on the other hand). Byakuya has short blonde hair and wears white framed glasses.
If you want to don simple anime costume and also into spectacled characters for cosplay conventions, this danganronpa Byakuya Togami costume would be a good choice.
