Thanks for the input, everyone.
Susie! I knew someone here had to have tried it...what with all the love we have for both Kamalikulture and fluid fits. Your experience seems to fit with the reviews I read. I would probably mostly wear this dress as a layering piece, so the extra volume and slimmer arms MIGHT be okay.
I think I'm going to stew on this one for a while. I need to harness my fall/winter wardrobe and then reassess my needs.
