So far, Warlokk hasn't been able to buy Seasons for himself. He has said many times that he plans to, but his personal time hasn't allowed him time to get the expansion pack. Someone (over at mts2, I think) has already made a couple of outfits for them to be Seasons outerwear, but so far that's all that's come out. Perhaps you could post your request
here and see if anyone that has Seasons now would be willing to do something for you.
