Hi there I live in a small down and the shops r rubbish .theres only m&s here to get measured. I’ve measured my self at home and I’m 31 under bust and 38 over .so I went to m&s she measured my under bust only and told me I was a 36 Back I was like that’s gonna be too big I no. So she trotted off and brought back a 36 back with guess what was far to big which she then said that there must be an abromallity with my rib cage . I’m so stressed out and upset as I no there nothing wrong with my rib cage so I still don’t no what bra to get xx
