Maxi short sleeve pocket mod sunflower yellow retro vibe elegant dress

UOOZEE (uooze.com) maxi dress Purchased online at uoozee.com (listing still available to view online). 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 19" (so ~38"); waist is 17.5 (so ~35"). It looks cute w belt as well (belt mine, not included).
