We did BBB yesterday and it was fabulous! My 4 year old said, "Mom, I did not just like that. I really, really, really, super duper liked it!"
All the classic princess dresses were there except Snow White and Belle. Oddly enough....they aren't currently carrying Snow White dresses (blasphemy!!!), although Castle Coture has a couple left over, all size L and XL though. Seems weird that Belle wasn't there though bc that dress was everywhere else! I have to imagine it is usually there.
My girls dressed as Princess Aurora ( it had long mesh pink sleeves, but she didn't seem to hot or anything at all throughout the day), and Anna! There was also...Cinderella, Sophia, Tinkerbell, Ariel (green dress), Tiana, Jasmine...and I feel like I must've forgetting some. I saw Merdia dresses in the shops but don't remember if they were in BBB.
My biggest shock was not having Snow White

Not sure when they plan to carry that again...but I would hope soon! She is classic!
If I remember, I will try to snap some pics to share of dresses at some point. Didn't cross my mind the last 2 days, sorry!!
