Dodo Bar Or jumpsuit floral Size L but will only fit a 6-4 Vneckline plunge back. Beautiful jumpsuit does not fit me I’m a size 8 my waist is a 29 but it would be to tight on my thighs. First someone that’s a size 6-4 or small not a medium. If you would like measurements please let me know. There’s a small hole where the bottom of the zipper is zipper still works no problem. Would need to go to a professional to sew the little hole or if you know how to sew. The belt is also a little floppy i don’t know why or if it’s supposed to be that way
