From collection of vintage handmade dresses with incredible detailing, here is a preschool / toddler girls FLORAL dress with back buttons in WHITE with GREEN, PURPLE, ORANGE, BLUE, with stretchy chest/waist.  Apparently cotton - no tag, as these are all homemade. Appears to be about a size 2-3 - measures approx 4.75" arms, 9.25" shoulder, 23" waist, 17.5" long, 21" chest. Beautiful, classic look for little girl!
