This is what I like to call thought out casual. I definitely thought about this, if I didn't, you would know. Probably because I'd be wearing gym shorts that I pulled out the dirty hamper and a big t-shirt. For the record, I don't recommend casual that hasn't been thought about, if you are going to be seen by many. Although, I can't say I haven't done it. Last week actually. Do I say, not as I do.
