I'm pretty sure some if not most of the vets here are costumers...I'm one, both a costumer and propwork/propcostume builder. mind you, I'm not a hardcore one as I have a day job but I indulge whenever I can.
I own and wear a TE ANH Sandtrooper [my third trooper suit], came in kit form and took me about 2 weeks to trim build and paint. That's me 2nd from the left, with the orange pauldron:
Also just finished my ROTJ Boba Fett, that took me about 5 years to get it just right.

Besides hard armor, I have a V for vendetta as well...:
I worked on props as well, sculpting and scratch building a Dr Doom V1 Helm that was available on the RPF. Reworked a POS PR, and am now in the midst of reconverting it again to a 'hero' as i've just managed to obtain a ACM Thompson SMG.
That's my 2 cents... :lol
Stay safe,
Tim.
