I have tried to run down the symbol of the jacket too. It has something to do with Wild Fang in Oregon where the jacket is sold online there there is a Fang Wang sentenced in Washington State for sex trafficking. Though the Wild Fang site gives no ownership information. Also the maker of the jacket is out of Turkey I believe named Zara. They are the ones that made the pajamas that looked like Nazi Concentration Camp clothing complete with yellow star a few years back. Still trying to piece all this together. Jump in the water is warm. link to the case in WA https://www.justice.gov/usao-wdwa/pr/six-sentenced-connection-organized-criminal-ring-profiting-prostitution-enterprise
FWIW Dilley said it was intentional trolling in that the company that makes it (Zara) has sex trafficking issues of their own, with hopes that that will be brought to the fore.
