The answer may certainly surprise you!
Double-stick tape is your friend!
Actually, we're kinda glad Iggy Azalea threw caution to the wind and decided to skip the tape when attending Rimmel London's 180 Years of Cool party in London on Thursday.
If she'd been more vigilant, we wouldn't have this glorious nip slip!
The Aussie rapper looked seksalicious in black slacks and a satin-lapel blazer held closed with a single straining button, which did a decent job of keeping her boobs under wraps through most of the party.
But when Iggy got in her car to leave the shindig, her nipple popped out to say goodbye!
