i use cts wardrobe, i think its easy but many say its complicated lol it lets you make a visual catalogue of your stuff but you do have to set it up so it takes some work

I use CTS. But honestly you don't need to buy anything now that there are folder thumbnails. You can just do it in-inventory, only put the items that should be worn in the folder, add your thumbnail, and always right click and Add/Remove to dress. I'm just already invested in CTS (recent plurk shows all my shoes, lol)
