This hat is by Balenciaga and is an impossible find. I believe is actually from the menswear line from when Nicolas Ghesquière was the Creative Director for the brand. A version of it was worn multiple times by Carine Roitfeld during that season and into the next and I have spotted her wearing hers even up to the last couple of years. 

The hat is made out of a dark brown corduroy that is top stitched around the brim. It is intentionally slouchy and soft so very easy to wear and travel with. A dark leather band wraps around the base of the hat and is secured by a black, gold and white enamel disc. It looks to have never been worn or worn very little. Excellent condition 

Tagged a brand size 59 and measures 22" around. Lined in a black cotton and finished with an interior grosgrain ribbon. 

Item# A379
