Lulu's black floral mini dress

Knot Sisters (sold at Lulu's) black mini dress with tan/ cream flowers. Has baggy bishop sleeves. The back is a bit open (I tried to take a pic but it's hard to see). Light material that's perfect for spring and summer! One flaw- the button on one of the sleeves is missing. It's sized as a Large but fits like a small so that's why I'm listing it as a small****
