Azazie Custom Size Bridesmaid dress

Brand is Azazie. Size was custom but can’t find exact sizes. It would fit any 5’7 size 4 or 6, possibly 8. Im size 10 now and it still zips up, though I can’t breath. It would be slightly big for a size 4 but could be altered. Only worn once. It has some dirtiness at the bottom of the skirt but it would come out if cleaned professionally.
