I know that the cowboy dress was introduced in an update several months ago. Since I don't have access to it, I assumed you don't get access to it unless you had the game on that account when the update went live. HOWEVER, I have a neighbor, about the same level as me, started her account the same time I started this current account, who has it.
I have the same situation with one of the three hour dresses - other neighbors starting around the same time as my account started having it, and I don't have it, nor is it listed as one I will get when level appropriate.
Am I somehow missing recipes?
