SHEIN Belle Crisscross Backless Dress with slit

I got this dress off Shein for a wedding I was going to but never ended up wearing it. it's still never been worn, only tried on. it's in perfect condition. It is a dark maroon colour and has Crisscross straps on the back. It has a zipper on the side and a sheer overlay. the underneath of it goes to just above the knee.
