78% cotton 20% polyester 2% rayon Size guide is on image 5. I knitted this with breathability in mind so it can be used in the coming season. It can be folded and stored in a bag! Easy to take with you for outings and travel! Also great for supporting your favorite idol or attending live concerts! There may be slight differences in color between the photos and the actual product. Please understand that there may be slight variations and distortions due to handmade nature. I make these so you'll be glad you bought them. #itokonnyakuhandmade #yarn #korea #koreanfashion #buckethat #crochethat #yarnbuckethat #handmade #summer
