I like them. I agree that colonial costumes were a better fit thematically for the pavilion, but they haven’t worn those for a while now. I think these are whimsical and are good for the arts festival.
Would I want them to wear these all the time? Not necessarily. I like the idea of having costumes that match the festivals though. They could save the patriotic colors they have been wearing for summer, and keep the Dickensian Christmas costumes, and do something special for F&G and F&W.
