Club Monaco one size black ruffle zip dress

This posting is for one used Club Monaco black dress. There is no size on the dress but there’s an “O” on the tag that might imply one size? I am usually a size 4-6. Ruffle collar with front neck zip. Back side has a slit. See second to last picture: there is some stitch witchery tacky on the inside that may come off after some washes. (I initially taped the slit on the back from the inside, then took it off.) Also, some of the hem has come off at the bottom (see pictures), which appears simple to re-sew. Dress is 33” from the top of the zipper (chin) to bottom of dress.
