Belle Badgley Mischka Sleeveless Dress, size 12 White Blue Geometric

NWT Belle Badgley Mischka Sleeveless Dress, size 12 White Blue Geometric with metallic thread details. Tried on and ended up wearing different dress for wedding rehearsal dinner. There is one loose thread on back (see picture). I didn’t notice when I originally purchased dress. If cut, integrity of dress seam shouldn’t be compromised. Nonsmoking; pet & scent friendly home. Happy to answer any questions!
