This hat is not adjustable. This item has some white marks on the underside of the brim, but I believe they may come out in the wash. With vintage & used items, please expect some minor flaws and use. Some of these items are older, and have been previously loved. Some items may have pinholes, stains, pilling, and/or normal wear. **All sales final, but please reach out if you have any issues with your order.** Smoke free home. Product is as IS and as shown in the photos. Please note that items were not washed before being shipped.
