I never thought I was fat or overweight as a UK 12 but I've always had REALLY broad shoulders. I have recently become a bridesmaid and given a dress with sweetheart neckline and one shoulder strap... I can hide some of my broadness by putting all my hair to the other side but, the problem is the back. The back is corset style and is literally at its most wide. The other bridesmaids are size 8/10 and although they have smaller sizes the gap between the cross cross is only 2-3cm. Mine is around 12cm with the chance of exposing skin if the flap underneath move in the wrong place 😔. I'm actually so embarrassed and since the dress is from China it only cost like £5-£10ish so I don't really want to get it professionally altered. I actually broke the zipper today pulling it down the qualitys that bad ><. It's not even because I have boobs I'm 34B. Only option is exercise! Any suggestions?? I do have a gym membership so equipment is available.
