Ordered a size bigger than i normally would and am very glad I did because even then it was a bit too tight. My head is kind of large and struggles to fit through the neck hole, but other than that the costume looks very good and I can't wait to use it for my cosplay. Be aware that the front and back bows attach via safety pin which may be kind of loose. If possible, you may want to look into sewing it on yourself.
The dress fits very well, however the bows are quite poor with loose stitches and are generally not up to standard. The gloves fit well though are tight in the arm. The crown runs very large and appears to be stretched out though the necklace fits well.
