Well, I tried one on, once. Does that count?

If you already limit yourself to still hunting, I suppose that sitting around in a ghillie suit is not much different from sitting around in fleece or down.
I, personally, wouldn't try to stalk an animal in a ghillie suit. But then, I'm getting too old to creep around through the underbrush anyway. Maybe it'd work for you.

I note that you want to hunt deer with a pistol at 80-to-100 yards.
But if you sit in the right place, in your ghillie suit, deer will come to you, and your shot will be closer—maybe much closer.
The ghillie suit was invented, I believe, to make a person look like a gorse bush in the open spaces of the English North Country and of Scotland. If the hunter sat very still, the deer wouldn't notice him, and might come close, because he looked like a gorse bush. Are there gorse bushes where you're going to hunt?

However, I am not certain that you really need camouflage, to still-hunt deer. As I understand it, deer see movement, not details.
Deer noses seem to work well, and a ghillie suit will not make you smell any different.

I saw Mickey Gilley in a suit once...does that count?
