THERE IS A POSSIBILITY THERE MAY BE WHITE LINE CREASES ON THE CAP. ALTHOUGH THEY MAY BE FAINT, JUST BE AWARE BEFORE PURCHASING. THIS IS THE REASON WHY THEY ARE CHEAPER THAN MY OTHER MAJOR LEAGUE HATS. PLEASE SEE LAST TWO PICTURES FOR EXAMPLE. This is made from a licensed fabric but not a finished product from a company. It’s single thickness. The fabric has been prewashed before making the hat. So the hat shouldn’t shrink. It is a single layer. I do not make custom sized hats. One size should fit most. They measure about 23-24 inches around and about 4 inches tall. If you have any questions, please let me know. Most of my hats are made from rare/hard to find fabrics at a great price. Images on fabric may be in different locations throughout the hat.
