Smocked romper

Medium rust/mustard yellow romper. Super soft, great condition. Tried on once and washed. I really needed a large, but they were out of stock, so I tried making a medium fit :( See pics for material, care and size chart. Faux tie waistband. Very stretchy. For reference, mannequin's measurements are 34 26 34. Measurement from tie to hem of shorts is about 15.5inches. Has pockets!
