Original brand new with tags.
Guys, this dress has pockets! Lightweight, wide 3/4 sleeves, beautiful "flower" buttons. The fit is wide / relaxed, so this size (EU 36) will fit perfectly even if you would usually select one size bigger.
For the sold out collection Kenzo x H&M styled this dress with ankle booties, but it can be worn over trousers as well. 
While 100% silk requires your attention and following care instructions precisely, this dress is quite a rare find, meaning chances you would meet someone wearing the same are few.
