Is it a Button-UP or a Button-DOWN? Let’s clear this up! Are they the same thing? No, they’re not. A button-down shirt has small buttons on the collar to keep it in place. A button-up shirt has no buttons on the collar. Button-down shirts are more casual and button-up shirts are typically dressier when it comes to menswear. I personally love them both!
