This dress is forgiving and very comfortable, it feels like I'm wearing a night gown :-)  The neckline plunges just like the pictures show, but it's far from obscene, considering the sleeves in the length, it looks pretty classy IMO.  The fabric is a little shearer than I was expecting, so wearing black underwear under the black dress was fine, but if other colors are as sheer, it might require a slip or something.
