This dress is so beautiful. The fabric looks like a vibrant vintage piece. The dress has a subtle bustier seam structure...vintage retro chic. Unfortunately, the medium was a half size too small and the large is a full size too big. At my best guess, a classic dress size 10 might fit the large, and an 8 with narrow hips/bum can fit the medium. I feel like the medium was built like column, while the large had a little shape built into the silhouette.
