JJ’s House A-line Illusion Scoop Floor-Length Lace Floral Evening Dress

No size tag on it but I am an L and find this to be a loose M or a snug L. I’ve take some key measurements as well: 17.5 inches wide at the ribcage area right under the bust 51.5 inches long from the back of the neck seam to the bottom 9 inch wide sleeves at the armpit area
