For my collection, I like to wear them. Being a Hawks fan that means Hawks jerseys I can wear to games. I have a pair of ultrafil Devils jerseys from the 90's when Scott Stevens was one of my favorite players. I had a few Kings jerseys when I lived in Los Angeles to wear to games and now I have a few Caps jerseys to wear to games in DC. Aside from that, I don't really do other teams. I've bought and sold classics like Avs starter mesh and Rangers CCM mesh where I loved the design and aesthetics, but if it just sits in my closet, what's the point?
Regarding jerseys for teams I dislike, as much as I love Chelios, I would never buy a Detroit jersey. And regardless of how much I love the designs, the same goes for the WC Blues jersey, Vancouver Millionaires or 40th ann jerseys. If I think about other sports, that would be like me getting a White Sox, Packers, or Patriots jersey. NEVER gonna happen.
