I posted this company awhile back for Puggaree Levine hat company St.Louis, dupioni silk! There is a company in the UK that will produce school and club colors,also bespoke suits and tuxedos. If you have a true interest in finding something you will find it!!! Maybe call your Mom,she will find it for you. No offense
The other alternative is to roll your own true pugaree. I did it for one of my hats. I'm on the field telephone now so limited asto what I can post, but if you Google <the fedora lounge make your own pugaree> you should turn it up. I only needed a few feet of 1" drill cotton tape (any John Lewis or similar will have it for buttons) and a pin to hold the end in place to begin. Easier than you'd think.
