Beautiful Navy Lace Dress

Worn once for a wedding, navy lace dress with silver underlay. This dress has a modest neckline and a seam at the waist to draw the dress in. There is a silver exposed zipper in the back. The detail in the lace is stunning! Measurements: 36 inches from shoulder to hem 21.5 inches from waist to hem 16 inches armpit to armpit 14 inches across at the waist I believe it is either a size 4 or size 6. The tag is not in it.
