I had to wait over a year for the head and hands to come in (the maker had us all convinced it was going to be a 3 month project...)
The suit and everything else was pretty easy. Gray slacks, same boots I use for the majority of my other costumes. The jacket was a little effort to get together, I just happened to have a not approvable officer jacket that someone gave me in a big bundle of other items, so we modified it to be accurate.
And now I was the first 501st Bith and I'm the CRL model. Thank you for asking and the compliment.
