Set of 3 Bridesmaids dress w/ off shoulder straps

Beautiful formal gown with off the shoulder straps... this is for a set of 3 bridesmaids gowns... straps did not fall off due to the way it’s made ... we each paid over 300 for each and trying to recoup a little money but pass them on. Smoke free home. I was told by the formal dress shop that formal gowns, you always size up so here are the sizes that are on the dresses but what size we actually are: Size 12 which really fits 10 Size 14 which really fits 12 Size 14 which really fits 12 They are hanging now but when purchased, they will be received in a box and need to be hung and steamed.
