I have a hat for trade too. Would love to hear what ppl would give.
I am looking for a dress with matching hat. That would mean either a pointy hat in the same color as the dress (I have seen pink and purple ones and the blue sorcerer's ones), or the princess crown that would go with any color dress. I have read there are shoes to go with the dresses too.
The black satin top hat (Haunted Mansion?) that looks smokin' with the yellow dress is actually my favorite!
I also think the Indian feathered head dress is cool if you want to negotiate a package for other quest items. Does it have an outfit or is the black and brown one the cowboy suit? And is the white and gold suit the diver's suit? I like that too. But dresses are my first priority. FYI, I no longer have a cannon room or snowman to trade.
