ME2 Garrus with battle damage. This does not include the head gear. I wore this to DragonCon many years ago. Some of the glue joints have failed, but this costume could be restored fairly easily by the right person. It has lights and digitigrade footwear that goes over your shoes. It is made of vacuum formed plastic mostly.
I am offering head gear kit pieces in the garage sale too.
You can see photos and video of this in its prime at wickedarmor.com
