Torso area too small for me. . . wouldn't zip all the way up

dress is very pretty and fit fairly well once i got it on - zipper was great until i got to my chest area and it was a struggle to get it all the way up, so if you have a large chest just beware! i think going a size up would’ve been too big for me in other areas, so i won’t be returning for a diff size. once it was on i could wear it, it was just a bit snug in the chest. i am a 40DDD for reference, maybe even a little bit bigger ngl
