@mari_thomas_welland: ✅ Cup letters are relative. A “C” just means your bust is a certain amount bigger than your underbust for THAT band size. So these are all “C cups”… but they are not the same boob volume 👇 28C → 30C → 32C → 34C → 36C → 38C As the back size goes up, the “C cup” gets bigger too. Read this slowly because it’s the “WAIT… WHAT?” bit: If you wear 34C and the band is too loose, you might actually need 32D (same cup volume, smaller band). That’s a sister size, and it’s why your bra can feel “wrong” even when the letter looks “right”. ✨ The wild part? Two people can both say “I’m a C cup” and one can be much fuller than the other… because they’re on different back sizes. If any of this sounds familiar, you’re not alone. ⬆️ Usually the issue is the band size + cup volume combo, not your body. 🗣️ Comment if you learned this today or if you already knew… I’m curious. Save this for the next time bra shopping makes you question reality 😅 #BraSize #BraSizing #BraFitting #BraHelp #BraTok
