A very last minute costume. Not 100% accurate due to the last minuteness to make because of a group cosplay, but I'm very satisfied with the outcome!
I found the top and the pants at a Goodwill and the beret and holster at a surplus store. The beret and shirt both got dyed blue (or darker blue in the beret's case), and the patches were sewn onto both. Then I made an iron on for the back of the shirt with the STARS police blurb.
I had the belt and the boots already kicking around (fun thing about the belt is it actually has the negative shape of a horde of zombies on it).

The armor and the gun were both shaped by my husband out of EVA foam. He painted the gun and I painted and added the rivets and straps to the armor.
The wig, again is another thing I had kicking around for forever. So I chopped it short and hit it with a bit of hairspray.

I may make a few adjustments before I wear it again, and do the second belt she wears/her pouch, but again, I'm very pleased with how it looks.
