H&M silky black mini dress with illusion neckline

Super silky (seriously, the most convincing imitation silk fabric ever!) short black dress with flattering sweetheart mesh illusion neckline and slight keyhole back. Great condition except for one tiny run/hole where the store tag was (see third pic) - not noticeable when wearing. I cut the neck tag off so it doesn't show through the mesh back, but it's H&M, size 2.
