Had 3 DC in 4 years and have lived in crop tops and gym style bras. Vaguely remembered seeing a Bra Intervention thread on here yonks ago and thought I would get myself measured properly once I had finished breastfeeding.
So I pootled on down to M&S. The woman measured me; 29 under bust, 34 on bust. "ah, you're a 34A" she says, and gets me one. I couldn't remember exactly what the bra intervention threads said, but I knew that didn't sound right.
Came home, found the thread, went back out and tried on different ones, and ta-dah, 30DD fits fantastically. Comfortable, good shape, no back fat or overhang etc etc.
But I'm mad at M&S for their shit fitting! Would you email customer services to tell them their staff need retraining?!
