It occurs to me (who dresses in shorts and a t-shirt) a good market that might be worth exploring would be costumers, like on Broadway, Theater, etc who has a warehouse of wardrobes, and needs to pick some things that convey a certain atmosphere for the performance … maybe theme based Operas. Runway model manager,. people in charge of choosing wardrobes for public performances.

I sincerely hope your endeavor is successful and you reap the rewards.
