Guys I really want to buy an alpaca jersey

I'm currently in Trujillo for a medical elective. I have looked all over the city to find anything alpaca to no avail. I have the option to drive to Huaraz and probably any other city within that distance but would hate to get there and not find what I'm looking for... Cusco and Arequipa are too far unfortunately. If anyone can help me I'd be eternally grateful

Cheers
