A lot of people take their underwear for granted, but having the wrong pair on can make you uncomfortable all day. It's okay to buy cheap underwear, but make sure it will fit you well. When your underwear starts bunching in the wrong places, or if it is too tight around your legs, you are going to start to squirm in your chair at work. No one wants to see you pulling and adjusting your cheap underwear at your seat, so be certain you're getting a pair that will fit you. Otherwise, your cheap underwear will lead you to an embarrassing situation.
