I mostly use a leafy type mesh jacket over, well, anything from a long sleeve wool sweater, to a dark cotton T-shirt, depending on the weather. While not as good as a full blown ghillie, it does a pretty good job of hiding me. I never could get the hang of shooting with a ghillie on. Something was always snagging on briars or getting in the way of my bowstring. Plus, they are hot as the dickens.
For pants, I just use cargo pants. I have some that are camo, but my favorites are Duluth Trading military style.
