It doesn't fit right, and I altered it to fit right. There's another thread about this...

I wouldn't alter it to make it tighter though... I cut some material and hemmed the bottom of the gunshirt, to make it shorter, but it was hanging around my knees. I brought it up to mid-thigh. Less to tuck in. Also, the pants are designed for guys straight-ish bodies, not the female's curves. It just didn't fit right. Now it's as comfortable as can be, and looks the exact same as all the others. Gunshirts have no give in the chest, let it out, tuck the wait in, equals less to belt up, less bulk, less heat, and less chance of passing out on parade.
Also, on offering the same services to the other females, I do the same thing. Less bulk, fits proper, more comfortable. Once the Cadet program comes out with either a tailoring service, or a uniform line for females (see link), I will continue with it.
EDIT: To add afterthought... :facepalm:
