the tinny pink star pick is from one of the Petites sets- likely Ponytail Petites, Glowing Magic Petites, or Twinkle Petites
I've seen the white comb and blue star pick with fakies before...
Purple Barret on her tail is from Ribbons + Lace Pretty Ups
Teddies Barret is from Kittens + Teddies Pretty Ups
Pink Bow with white hair is from Ribbons + Lace Pretty Ups
Yellow dog with blue hair is from Kittens + Teddies Pretty Ups
Yellow lace bow is from Baby Starburst
I think the show cap is from the Scrub-A-Dub Tub
Tu-Tu is from Prima Ballerinas
Hope that helps a bit
