The cords look super Tanya! I think you can definitely get away with the smaller size, but after reading this thread, I get the feeling that you would feel more comfortable in the larger size (which still fits you perfectly in the picture, and taking in the waist won't be a problem, right?).
I actually vote for the red dress (can you wear this shade of red Tanya, just wondering, because I think for me it would be a bit too 'warm'). You look wonderful in the black one, but you already have the other tunic dress in black. And I really like the contrast of the black belt with the red, if anybody can get away with that, then it's you! Please try it?
It would look fabulous with black skinnies and a black turtleneck indeed. I want pics!!-)
Btw: I love those Gabriella Rocha shoes too. And both the DVF dresses, one for you and one for Ana;-)
And you girls are making me hungry. First a chocolate buffet and now Ana's brunch. Yum!!
