NWT royal blue beaded high neck dress

Gorgeous brand new dress from Eva Mendes’ line for New York & Company. Sleeveless royal blue, with a high neckline with intricate beading around it. Two buttons in back. Extra buttons in package attached to tag. Falls at my knee (I’m 5’4”). Originally size Medium, but had t tailored to fit me, so truthfully size XS/S. (Marker marks under arms from when I had it sized. Not noticeable once on at all. Will possibly wash out?)
