If the deer didn't smell you, it wouldn't have smelled you under any conditions. In certain conditions, they will smell you, no matter what you do, and other conditions you can get by with anything. Try to keep your clothes as scent free as possible and take a shower with scentless soap before you go hunting. Keep your clothes in a container until you are at the hunting area if possible and change clothes there. Or do nothing and you will still kill some deer, but you'll get busted a lot more.
