Well I tend to play as a breeder, so I have a lot of Sims born in game and then I try to find clothing to match their personalities.  Well I can't just have a Sim wearing the same thing everyday so each has to have 4 or 5 everyday outfits, 3 to 7 sets of underwear, a couple sets of workout clothes, a couple sets of formalwear, and some pajamas.  Before my previous computer went up in a flaming pile of poo (literally the power supply smoked) I had some 3GB of just clothes for maxis mesh skins.  I had a bunch of other clothes for Warlock, Simmergirl, and Beosboxboy meshes.  Well to make a sad story short I am trying to rebuild my collection and having quite a bit of fun doing it.
