SUPER RARE NWT Ann Demeulemeester Versatile piece

What is it? a Dress? a Jacket? a Coat? a Skirt? a Romper? Pants? It's ALL OF THE ABOVE!!! Amazing garment by Ann Demeulemeester, one that captures her essence as a designer like no other! If there was 1 Ann D. piece to have, this would be it! This stunning piece is connected with many drawstrings & buttons so you can wear it as anything, really! Made of 100% virgin wool, marked size 38 (US 4) but I feel like this is a Unisize 9/20/25
