I said i would write about my experience with MyShape so here goes:
The cardigan wasn't flattering at all. I knew it said it was lightweight, but I still expect lightweight garments to be substantial and this was just flimsy. The buttons weren't sturdy at all and felt like they would come right off. It was also just too long and looked sloppy. If it had been cropped, it would have been cute, even if it wasn't the greatest quality, but for the kind of trapeze silhouette it had, it needed to be much shorter.
When I went to return it, I filled out a form asking me about how it fit and for any additional comments I had. I basically just said I had a short torso and was petite and that I don't think the clothes I was seeing always took that into consideration. By no means is this a comment on the service or on the overall quality of MS, but at least this time around, it didn't work out. One thing to note is that I don't have all my measurements filled out in detail. There is a section where they ask for vertical measurements (from shoulder to waist, from waist to hip, etc). That probably would have helped. I will still give it another try if I find something else I like.
