It was made for measurements of 28.5-29.5 bust, 25.5 waist, 29 hips, and girth at 50 inches for considering the back/side sash, which can easily be adjusted or even cut. It is currently displayed on our mannequin with measurements of 29-27-32 (large child). As you can tell, we try to avoid bunching of fabric (“the diaper effect”), and you will notice that this particular costume has something under the top, this is extra straps. Whoever is the lucky dancer that get to wear this has the option of cutting that off, should it not be necessary. For resale value, extra is good.
If you are looking for a medium, we will be happy to try it on our medium mannequin as well so that you can see how the fit is there. Her measurements are 27-26-30 Medium
