Maxi long sleeve floral mod retro vibe lined dress

UOOZEE (uoozee.com) maxi dress Purchased online at uoozee.com (still available). It is too big and I missed the 14 day return window. The size is small, but it's more like medium. Actual chest (underarm) is 18.5" (so ~37"); waist is 17.5 (so ~35"). Belt not included as per original listing note. I do think it's cuter with a belt (black & clear belt as an example in pics, not included).
