I made one for myself this weekend, and it came together in about two hours. I want to make one using a jersey knit fabric next.
Pattern: Built By You, Top/Dress pattern
Fabric: Amy Butler
Mods: I added about two inches to the length. Next time I will add about an inch to the sleeves as well.
You can get these patterns at Joann's, just wait until they have their 99 cent sale!
