Hi yeah i know a lot of ya'll are thinking of how dumb am i to wear a nightie and not know the difference..for one thing, it was sold with other dresses and no it's not see through, it actually has an underskirt and the reason my colleague commented was due to the lacy neckline.. and i actually paired it off with a slacks and a cardigan, so no, i'm not working in a brothel though that made me LOL...people can have the silliest idea.. i'm still a bit convinced it's a dress, but nevertheless i'm not wearing it out any more.. cheers!
