Brand new black and gold dress with metal accents

Stunning material- black with distressed gold. Collar had bronze metal accent beading. Fitted top (zip up) and pleated flair bottom. Hits me just above my knees (I'm 5'6, 130). Is a size medium but would work better with someone with a slightly larger chest (I'm a 36 B and didn't quite fill it out enough) or you could have it altered since its zip up.
