White convert here. I cannot find anywhere one of these hats that fits onto my head. I have tried the basic flat prayer cap, the thicker squarer ones, the Turkish fez etc and absolutely none of them fit my head. I just cannot squeeze into it comfortably. I have seen other Muslims with huge heads way bigger than mine who still have them on but every single one I buy is made "one size" and they don't fit me. Do you have to get them custom made or something?
