Size: Medium (Accommodates 34" - 36" bust) and upto 32" waist. I cannot even get started on how deliciously pastry like this rainbow confection is - the pastel colors really pop against each other on this flattering babydoll silhouette. The panty has a perfectly elastic waist - good for 25" through 29" or so. Can accommodate hips up to 40". I also have this set in lavender/purple in SMALL size if anyone is interested - I'll get around to posting it eventually.
