You are not alone in this struggle. Every woman has a drawer full of bras that lied to her. That “invisible” bra that turned out to be visible under any light? We’ve got it. The push-up that made you look like you were smuggling melons? Been there.
For a low-cut dress, the answer is trial and error. Sometimes you’ll have a bra that works for three hours, then betrays you at a dinner party. That’s normal. Keep a safety pin, some tape, and a sense of humor in your bag. And remember: if all else fails, just cross your arms and say you’re “being mysterious.”
