Here’s where the wizardry happens. Subtract your band size from your bust measurement. The difference determines your cup letter. One inch = A, two inches = B, three = C, four = D, five = DD, six = DDD. Yes, it’s like alphabet soup, but you’re the chef.
Let’s say your band size is 32 and your bust is 35. That’s a 3-inch difference, so you’re a C cup. Congratulations, you’re a 32C! If the difference is 5 inches, you’re a 32DD. Don’t freak out about as, bs, or dds—letters are just letters, and they don’t define your worth.
