Nope. That look actually has begun to annoy me. So many guys in.high school did that every single day..and I felt it was such conformity, and it wasn't even attractive to me very much. I also thought it made them boring not to have any kind of mind of their own and to wear the same style all the time. Idon't mind it every once in a while, but when a guy dresses like that every single day, I don't like it. I like variety. So no worries if you dress like that sometimes, sometimes being the key word. But, I wouldn't get in the habit of doing it every day. Just my opinion!
My boyfriend wears that look (except not slippers, always tennis shoes of some sort) when he doesn't wanna get dressed up. But usually he wears khaki shorts instead of basketball shorts. The bball short look is fine for a while but I like to see guys dressed up more too.
