I just finished (except for hemming) the New Look 6429 faux wrap dress and it turned out nice. It was the first dress I've made and was pretty easy. Per suggestions at patternreview.com I went down a size and also took the skirt in some so it was more figure flattering. I'll post a picture once I hem. I like all the variations they give you with this pattern.
I've also been looking for a shirtdress pattern. Here's two I've considered that you could alter so it is just a skirt on the bottom without buttons:
Hotpattern Expensive and this is sort of beta. According to patternreview.com there are often drafting or direction problems since this is a new company.
Fitzpattern Cheap but not as shapely.
