I tried it on once and then stored it in the closet. There is no yellowing on the inside. There is wire in the brim, so you can change the shape as you like. I think it will go well with both pants and dresses! I will fold it when I send it. It was also folded when I bought it! There are some creases, but when you wear it, it will conform to the shape of your head, so I don't think it will bother you too much.
