I’m a millennial, and I still dress all emo even in my 30’s. My 20 year old coworker even complimented my black skinny jeans with zippers in random places the other day.
No reason to stop loving your late teen/early 20’s aesthetic! Don’t let the world crush your creativity, do you and to hell with everyone’s opinions!
At 35 I continue to wear home made stenciled t-shirts and jeans I cut into shorts. If my boss doesn't like it he can go break a hip about it, how I look has no bearing on how well I do my job.
