I ordered my dress based on custom measurements.
What I like: Flattering cut, feels solid and well-made when on. In general, it fits.
What I feel neutral about: The dress itself is also a bit longer on me than pictured -- it falls a couple inches below the knee.
What I don't love: The neckline is extremely low on me (with a large bust), and the back and straps are somewhat loose. However, it looks like it should be possible to shorten the straps and take the back in a bit, thereby fixing the neckline problem. I expect that has to do with the pattern not being designed for a large bust -- the dress fits insofar as it matches the measurements I submitted. It seems that the software responsible for the extending the pattern simply didn't take cleavage into account...
Overall: A much better starting point than anything I could find in the stores, but it will need a fair amount of work before it is perfect.
