is this what you're talking about? http://www.nexusmods.com/skyrim/mods/48375/? I don't know what mod you're referring to, but the latest version of SkyUI has the ability to let you define equipment groups, which can include complete outfit sets, and let you switch between them with one keystoke. what i used before was a mod by itself, that was a while ago. I didn't know skyui had it maybe they added it since then, thanks.
