Selling to organize my closet. I've only used it twice since I bought it. I've stored it carefully to prevent it from losing its shape, so it's in relatively good condition. I measured the black fabric on the inside, and it's about 56cm, but please consider this as a reference as it's a rough measurement. There's an adjustment ribbon inside (see photo 6). It has a simple design with a slightly asymmetrical brim, making it easy to style. This item is close to the maximum size for shipping, so it will need to be folded in a few places for packaging. Please be aware of this. If you prefer shipping without folding (in a dedicated box), it will be an additional 300 yen. *Will be folded and shipped in simple packaging. 14+ (Ichiyon Plus) Hat Hat Fedora Straw Linen Jute Hemp Grosgrain Asymmetry Spring/Summer UV protection Straw hat color...
