Soooo cute! Good pre-loved condition Labeled a juniors size 9/10. I'm 5'7" with long legs and wear a size small-medium...this fits me decently but I don't quite fill it out all the way. Would fit a bigger medium to large better. There is some stretch to the material Measurements: Armpit to armpit: 15" Armpit to waist seam: 8&1/4" Waist seam to bottom of jumper: 13.5" Waist: 13" across Hips: 16" across
