H&M ‘like-new’ seersucker top

H&M seersucker off the shoulder balloon sleeve top. Worn only once. 19.5” pit-pit, 18.5” length, 17.5” (without stretching elastic) at neck/shoulder & approx. 19” stretched. Fabric composition as shown on tag in pics. Tag says size 10 but I believe it would fit size small-medium.
