A set of a floral hat and a white frilly (Q-Pie) hat. The items were hardly used and have become too small. Stored at home. The white hat has a size indicated; the floral hat has no size indicated, but it's about the same size as the white one. I think they are suitable for babies aged 0 to 1 year old. They have chin straps, which are the tie-up type, not elastic.
