Missoni jacquard dress in blue, yellow and black

Excellent used condition Size 46 which website states is US 14-16. I wear an 8 and feel very confident in this. Form fitting and falls at sweet spot just below knee. I am going to post as a 10, but 8 could wear as well as 12. PTP 18 inches Length 39 No fabric tag but stretch- other websites say this dress is cotton ( I’m not so sure) It is missing the black sheath dress it typically comes with - priced accordingly. Do not see need for sheath. Let me know if you have questions.
