I think that's perfectly fine. From a style stand point it can be viewed different ways though. If it is clean, tailored well, and looks adult then you'll look suave but it can look a little rag tag or bland.
I don't think dressing like that is bad though because I'd hope someone doesn't spend all their time on clothing anyway..and think like Dr. Ian Malcolm..life is too short to wonder what you're going to wear0
