Because I'm also on a budget, I was piecing together the costume from Hot Topic purchases since 2008. I had the trench coat, hexagon shirt and tie from that year TDK came out. The whole costume went on a back burner as I didn't have enough income to order custom made pieces to finish it.
Suddenly, Hot Topic remade some pieces and issued new items too! Everything for this year: trench coat, hexagon shirt, green vest, and pants (wrong color stripes). Everything except the pants sold out in days. I managed to call a store that still had vests and I went to try them on and see them in person. It's a nice velvet fabric. The new trench coat is seems like bad quality compared to the one I got from 2008. Check a Hot Topic if you have one close.
All of the Hot Topic pieces are just "close-enough" parts though, so if you're looking for more screen accuracy, that's going to be difficult on a budget. I absolutely love the vest. It's lacking the correct number of buttons, but I plan in taking them off and sewing on more correct style buttons anyways. I had coupons and Hot Cash to help with the costs.
For now I'm missing socks, suspenders and shoes.
I ordered a pair of gloves on Ebay just last night. I had the old Rubies kids sized gloves because they were the only ones that fit me :lol. (

I don't know how long these have been released but I noticed DC started to make suspenders based on the look from TDK (not screen accurate). I plan on ordering some soon.

Hope some of this helps, lol. Good luck on your builds!
