I have a Volante Next Gen-style Trek jacket. It's awesome, high quality. It's subtle enough that non-Trekkies don't notice other than it being nice-looking, but Trekkies will recognize its homage to TNG. I've been stopped on the street multiple times already by random Trekkies asking me where I got it, lol.
It's really expensive though (315 USD)
Also relevant: When Kate Mulgrew surprised everyone at an AOC campaign speech before she got elected.
