I tried on this sweater dress at Macy's today: http://www1.macys.com/shop/pro.....#038;pla_c...

And even though it's not a fit and flare, I thought it worked quite well on my pear-ish body--the knit is quite substantial, so it's not too lumpy and bumpy, and the top popover feature means that top and bottom halves are quite balanced. Also, it's very warm--so many sweater dresses I see are not actually that substantial, but this one is.

The dress that I tried on had a few snags (probably due to it being the display dress with a longer hanger that was incredibly hard to get out of the dress), so I ordered it online instead. I'll post pictures when it arrives!
