Marc Jacobs Seafoam and blue Grecian-style dress

This is absolutely stunning! Knotted shoulder tied, Grecian-style bodice with flared and flouncy skirt. Abstract floral design. I cannot read the fabric content but it does say “dry clean only”. Invisible side zipper. There are 2 stains on the ties that I did not try to remove. They are not noticeable when tied. Pit to pit is approximately 14”. Marked a size 6 but seems to measure like a small. Skirt is double-layered.
