Walking into someplace with a wrinkled dress shirt can be very embarrassing, and the excuse that "it's part of the style" only works so many times, if at all. You've got to keep your dress shirts pressed or else you're better off wearing a t-shirt. Some places won't even let you inside if you're wearing a t-shirt, even if it's one of those that look like a collared shirt and tie.
If you're one of those fools who thinks ironing is woman's work, just knock it off. You're a grown human being, you can learn how to iron your own shirt. There's nothing manly about needing a woman to do everything for you, even if some of those things are traditionally roles for women. I don't know about you, but I like to rely on myself instead of being a dope.
