This is not your typical button up. Okay, maybe there are similar features. Cotton is standard, and yes, it does have buttons and sleeves. But style is key for a collared shirt. I want something that looks nice without me looking like I'm trying to look nice. As you slide each arm into the sleeves effortlessly, you might as well enjoy a post coitus cigarette, cause this laid back look just feels relaxed all over. Keep the sleeves down or bring them up to the designated area to show that while this is a collar you have on, you're not afraid to roll up your sleeves and do work. I have an athletic built, 6'0, 170 and when the guns aren't on display, they're protected with style. The medium fit me well, but I would be hesitant to stick this in the dryer and risk shrinking. But if that happens, just roll'em up and you're back to party mode.
