Worthington tank blouse small

Please see photos :) I just bought this pretty top off Mercari (first photo is mine, others compliments of Mercari seller) but it isn’t quite long enough for my comfort level :) 17.5” across 24” top to bottom. The ruffle does add a little flare at the bottom, and it’s a definite teal - brighter than the photos shown. Interior longer layer lined, super soft. I would agree it’s most likely a small :) Thank you!
