OK, here goes . . .
First of all, I'm seeing what looks like seams at the shoulders and the elbow, and what looks like "edging" under the logo and round the rib cage under the chest, but they don't really stand out, assuming they're part of the design, and can't really be seen well unless you zoom in close.
Then the logo looks too stiff. IOW, the bottom point looks like it's bent and you can see the bend, though that may just be because of the shine. It also looks like it sags in the middle, and the maroon colored bottom of the S looks like it's got a sunken area as well. I think it looks too stiff for the kind of "fabric" it's attached to.
As far as the skirt goes, that would look so nice dynamic, but I'm not sure if you're into doing a "hybrid" outfit. I know you were concerned about the folds in the cape, and the skirt's going to have the same issue.
Lastly, I think the emblem on the skirt should have a metallic look, or make the S a different color, because it hardly shows up.
I do like the squared off neck, rather than the usual circular shape.
OK, that's my 2¢ FWIW.
