Snow camo would be a tyvek suit from lowes and some spray paint worn over my warm clothes.
I usually hunt in jeans, boots, and dark brown or grren shirts or jackets. Since I have to shave for work I consider a headnet mandatory and i wear it backwards and just look through the mesh.
Another thing that I use alot is a piece of camo fabric tie wrapped to some fiberglass poles. This way I can stick them in the ground and have 360 Degress of concealment.
