First up is a Marcy Tilton pattern Vogue 8904.
According to the reviews online this pattern has a lot of negative ease. Keeping that I mind I sized up size 16 on top and a size 18 waist down. It worked out perfectly. Also, Communing with Fabrics blog has a wonderful step by step on how to layout and cut your fabric. I followed it rather than the directions.
The pictures on the dress form are terrible as the dress didn't fit well on it but looks amazing in real life and I got lots of compliments.
I purchased the fabric from Girl Charlee, it's really nice fabric. Too bad the shipping was so expensive or I would be ordering most of my knits from them.
