Pretty, pretty, pretty. I suspect, but am not sure, this is a cotton/silk voile. Cotton is shown in the materials section, but the description says it's a silk mix. It looks like a voile, and silk is often used in voile to give it a smoother look and better drape.
The style is just too sweet. I love the dropped waist casing and drawstrings. It can be left loose to hang straight to mid-calf, or cinched in to create tiers. And the skirt has a built in slip/lining. Perfect for hanging out at home, running errands, or going to a party. My kind of be-whatever-you-want-it-to-be dress. This Etsy shop, cocoricoo, is described in the profile as a group of young-at-heart designers/makers. The writer stumbles a bit over the English words, but the designs at the shop are definitely multilingual. This one is $48.00
