I see in your profile that you like Harvest Moon -- you can probably easily thrift an outfit for one of the MCs (especially the older ones that mostly just wear overalls and a shirt), or one of the townspeople (you could probably even choose depending on hair!), and since there are so many games with so many different designs, you can easily find something that works.
I always see at least a few HM cosplayers around Fanime, and I know that there is always a HM/RF gathering (I think it is Monday this year?), so I'm sure that someone will recognize you. I wouldn't know much of anything past BTN-era, but I know that I;d stop and take a picture of you if I saw you in a HM cosplay that I knew.
