I didn't really mind the damage to the box or the smell of the hat itself. But it took a long time to arrive. Also, the tag with the word Balenciaga on it was upside down.
I usually wear size L, but if you want an oversized look, I recommend going up one size. Also, the button direction is for women because it's a Miu Miu. The fabric is sturdy and doesn't get crumpled even after washing.
