Don't get too hung up on the clothing thing. It's not a fashion show. If you're going to be wearing blaze orange, then IMO spending a bunch of money on camo is a waste. Just wear warm clothes. If it's going to be cold, dress in layers. I hunt wearing a suitably warm coat for the temps and insulated bibs (like Carhart, but a different brand), with several base layers. As for the whole scent control thing, I don't even sweat that too much. Paying attention to the wind and staying down/crosswind to the deer is your best bet. I've seen (and shot) more deer without using all the fancy scent eliminators than I have with. Some people swear by the stuff, but I think that working the wind is more important.
