Missguided Black Mini Dress

NEVER WORN BEFORE. NEW WITHOUT TAGS. Missguided black cut out design dress with mesh. The sides are see through so it would probably be best to not wear underwear! After I bought the dress I realized that the thread near the cleavage (where the red circle is in the last photo) seemed to become detached, but it's not noticeable and I honestly don't know what it's purpose is, so it could be discarded or sewn again. zip closure in the back.
