I feel like that a lot. For instance, right now I think it'd be super fun to make a Skuld (Ah! My Goddess) cosplay, but I'd never wear it because it wouldn't suit me well appearance and age wise. It would just be really fun to draft and construct! Maybe you can find a friend who wants to wear the cosplays you make, or you could even try to sell them or something.
