This costume was gorgeous and has so many of the adorable details we love about Ever After High. My daughter is 7 and petite but I thought I'd order the 8-10 just to be safe. It's a good thing I did because it was extremely small for the size. Luckily, it fit her perfectly but I have a hard time believing an 9 or 10 year old would fit in it. Absolutely beautiful costume though and very true to Raven Queen. My daughter loved it!
I originally ordered the medium because my 8 yr old daughter fell in the medium size. When we tried it on the costume itself was way too small, but the accessories fit perfectly. So I ordered the large. The large fit nicely except the accessories are way too big. So I'll need to alter the belt and cuff.
