Donna, IK, Jeanie, Suz and Greyscale, thanks for your comments and tips. Yes, Donna, trying another belt style is a good way to add some variety and I think it would work.
IK, you're right; I am feeling great about these selections and I guess it shows.
Jeanie, thanks for your exclamation points!!! That always feels good.
Suz, I think the HL dress will work with different shoes and while my preference is to wear the Okalas, of course, that is impossible in NYC in mid-December, so the Aquatalias will be the way to go when we're out.
Greyscale, I think you touched on something about the "shift style" and that's why it works. I hadn't thought of that, but this may be why it feels so "fluid" on me. Thanks for offering that.
Gp, as someone who often wears dresses often, your comments mean a lot.
Gryffin, I'm so excited you like the HL, too. Yes, it is the Helmut Lang "Nova" Jersey Dress and it's on sale now on the Nordstrom site, although there aren't many sizes left. I did order two sizes, a small and a medium, and what you see, above, is the medium, so I did size up. Honestly, I probably could have sized up to a large and that still may have worked, but since I have narrow shoulders, the medium was fine for me. I hope you can find the size you're looking for.
Mochi, thanks, and next time you come to town, maybe I'll wear one of them.
