This dress is www.marksandspencer.com/beaded-neckline-chiffon-tunic-dress/p/p22322872?colour=Black lovely and very flattering. I have it. I wore it to an evening do with some matt black tights and platform suede wedge mary janes. I got lots of compliments and felt very simply dressed but well turned out.
