My tits..Lord help me

So I've been wearing a 34D for some time now. But the bra was falling apart, trying to kill me basically. The underwire is poking out on both sides and none of my bras feel right... Smh. So I decided to go to a fancy bra store and get fitted. I'm expecting them to say I'm a 32DD or something.Girl...I am a 28F WHATT!? WHY?! No wonder I have back problems. I can't find that size in stores 😫 Just great. Plus bras are hella expensive. So yeah just spent over $100 on two bras.
