I got lucky and had a local garrison member with pieces, that was not going to finish the build. She had acquired them second hand herself, and origanl source is unknown. Checked CRL and build threads, and they are accurate, so using them.
After helping hubby (the actual Pencap510) with 2 builds, one being TFA for movie release, and another year of helping troop, decided it was time for my own costume. I thought about Resistance Rey, but want to be 501st, so searched the CRL's for the costume to called to me. Zam did, in all her purple glory. A few weeks of reading 'decade-old' build threads, we took the plunge.
I ordered a faux leather jacket off Amazon ($15), hoping to alter to work for the vest. Future ambitions have a real leather vest, but I want to be more sure of myself, and sewing leather is a little scary. Got the jacket, removed the sleeves, collar, bottom cuff, and lining. Trailing some acrylic paint to get the lilac grey I'm looking for in the vest.
