This.

Velocity has an Ultra-Low Viz (ULV) kit that has a grey plate carrier and a white tshirt style carrier with plate pockets. It's a pain in the ass to get into but, depending on your build/body type, you can wear a polo over the top of it and no one would guess you've got rifle rated protection on.

Just remember the rule of hard armor: Thin, light and cheap. You get to pick two.
