You’ve probably heard of a “Titan” cup size—like the one worn by reality TV star Annie Hawkins-Turner (who holds the Guinness World Record for largest natural breasts). Her bra size is often cited as a 102ZZZ or something equally bonkers. But here’s the truth: that size doesn’t exist in standard sizing. Her actual fit is custom-made, with a band size around 50 and a cup that’s basically a small parachute.
So the commercially available largest cup size is generally considered K, L, or M, depending on the brand. But if you’re talking about any bra ever made? The sky—or the bust—is the limit.
