I think Molly's Aviator outfit is on the way out and also Kit's Tree House outfit. They were both at the Oshkosh Warehouse sale in June when I went there. Being at that sale is a sign of future retirement in my opinion.

Kirsten's Purple Plaid Dress and Molly's Route 66 outfits were NOT there. I think Kirsten's and Molly's are newer. Kirsten's older short story outfit, the blue plaid dress with yellow shawl, has already been retired and I believe that outfit would have been the one from the Aviator time frame.
