Oooohh! I love the cardigan over the dress! That dress is amazing on you, and those boots are to die for. Your legs look fantastic!
I think it looks very nice unbelted and unbuttoned over the dress. I prefer this to the other look with the pants. It's a good work outfit. It may also look good belted (with the right belt), but I do like it without a belt over a dress.
Nicole, you need to get more dresses!!! I know it's tough to find ones that fit, but you totally rock a dress.
This makes me wish I'd bought that boyfriend cardigan from BR I tried on - twice - but didn't buy. I didn't buy it, because I didn't like the lumps and bumps of my jeans underneath. Now I wish I had bought it, to wear over a dress.
Regarding your questions above, the idea is to wear the cardigan unbelted, with a belt over the cardigan. Here is an example (and I wish I had a sheath in this exact shade of red... it's yummy!):

Snow: it's raining here now - washing away all the snow we got this morning. It's a mess out there, but I'm happy to see the snow go away. I did not have to go to the office for my meeting today, due to the weather.
