I've been looking and looking for "my" sweater dress for a couple of months and tried several on. I struggled with most of the issues Angie mentioned -- price too high, colour wrong for me, length too short (or long), fabrication itchy, etc. etc. Or it sold out in my size before I could pull the trigger!
I think I've settled on this one from trusty BR. It's soft, easy, and casual. Some reviews noted that it is "huge" but for me it was TTS for BR. It's meant to be a loose shift fit. It probably wouldn't work on those with a sloping shoulder line because of the cut. It's a bit shorter than I'd hoped for (on the knee vs. midi) but will work with flat tall boots and I'm planning to wear tights anyway.
Note - this silvery grey would seem to be a slam dunk for me, right? Well...it is, sort of. The thing is, I feel "washed out" in it without darker and brighter accents. This is a very neutral outfit -- I just put it on because I only had charcoal tights on hand and I wanted to coordinate. In future I will probably wear blue tights and boots and red and blue accents to liven this up. Or nude hose and silver jewellery and boots or similar.
Anyway, SUPER happy to have this.
