I was SO excited for a thin-strap version of the Ellie (and definitely recommend you go 1 size up from the Ellie size) but I didn't realize how different the navy crepe would feel from the cotton! It feels a bit itchy in the heat, traps sweat, and is overall not nearly as pleasant as cotton.
The style is not as fun as the flounces of the Ellie and the single horizontal seam at the bottom can look a little maternity-ish if you're not totally stick skinny.
