Are Push-Up Bras a Fashion Don't?

Last Saturday I was burrowing deep in my lingerie drawer and came across a high school-era relic: my very padded, very fuchsia push-up bra. Even though I hadn’t worn the physics-defying device in years, I hesitated to throw it out, which is when it occurred to me: Are push-up bras a fashion do or don’t? Rather than attempt to tackle the question myself, I conducted a rather unscientific poll of Who What Wear staffers and my family and friends.
