It's black, I lightened the photo slightly to see detail. Ever so slightly too large around the waist, and I clearly don't fill out the breast area as intended, but smaller would be too small on the arms and hips.
What would you wear to office? Leggings/boots/scarf/cardigan? I've currently got black ankle boots and black normal height boots.
What about going out for a meal?
Never had a black dress before!
