After reading all the size discrepancy I was nervous about what size to get. I finally measured her foot with amazon's kids foot size measuring print out. According to that she was a size 11, 11.5, although her shoes she wears to school every day are size 10 and still are roomy! So I ordered 11's and they fit perfectly. I could have gone to 11.5 to have growing room, but the 11's are great and I didn't want to deal with the hassle, we'll just know to go a tad bigger next time. And, she loves the flowers on the inside, she mentions them every time she talks to people about taking ballet: "And my shoes have FLOWERS inside them!" So cute.
