Nemidoor has some great plus-size dresses. This one is my favorite. Although I'm pretty sure the fabric is different between the two sleeve lengths. Definitely recommend the short-sleeved ones!

I also like this cardigan quite a lot. Haven't worn it many times yet, though.

Here's another open-front cardigan, kimono style. I adore this one.

I even miraculously got a pair of shoes that fits! These are my favorite shoes ever. They're basically a cross between Mary Janes and sneakers. And I find them super comfortable.
