We have the doll-sized and the girl-sized outfits and I would recommend them both, especially with them being on sale. They are pretty detailed for the price and really gorgeous. Probably more flamboyant that a true flapper outfit, but still adorable. The material can catch easily so handle with care.
I love the flapper outfit. It looks adorable on my Kit with her short hair. What's even more to like is that it comes with everything-including shoes!
I got the flapper outfit just before Halloween for Kit to wear and I think it is a great outfit. The only issue I had is that the delicate silver thread that goes round the neckline area was defective on our outfit in that it was detached from the main part of the costume on the back left side. I sent it back to AG and they replaced it--no problems. The shoes and crown are adorable as are the beads. If it helps, I'm seriously considering getting another flapper outfit while it is on sale to put away for when DD might want to have the dolls do dance performances or to have two flappers for next year at Halloween.
