Hmm.....I personally would look at Neiman Marcus, or Diane's website:

Also, I know Tanya gets some of them on sale at various online retailers. Neiman Marcus Last Call is great and you can order from them through NM website.

Unless you're VERY familiar with a brand, I probably wouldn't spend a lot of money to buy something designer from someone other than a reputable outlet. There are a lot of copies out there. Copies aren't necessarily bad, but you don't want to drop major bank on them. Does that make sense?
I just ordered a DVF dress, I'm so excited! I ordered an 8, which is the size I normally wear, but the style is A line and kind of swingy, so I figured it might run big. Even still it might be too small. Her sizing is all over the place for me--some shirts are true to size, and others (the wrap dresses as Tanya said) have been way too small. I've had to go up a size or even 2 sometimes. If you could afford it, ordering 2 sizes and sending the one that doesn't fit back would be a great way to go (unfortunately I have to order them one at a time in order to stick to my allowance).
EDIT: I just went and looked at the Julian wrap dress. That is a great dress. Very versatile. Are you thinking of the black or chocolate? You could wear it when you go somewhere without the kids, like on a date or something.
