Note: The design of this hat, particularly the shallower crown, was crafted to create a unique aesthetic that suits some individuals perfectly. However, if you notice that the hat tends to slip, I would advise attaching an elastic strap to ensure a more secure and comfortable fit. ✿*.Key Features.*✿ This is a wide flat brim hat!!
