I love Sheryl's outfit! The Little Black Dress is a classic wardrobe item, and Sheryl manages to make it a pretty, feminine, beautiful and perfectly accessorized biking ensemble. When I zoom in by clicking her photo, I see her looped earrings, starkly pretty white wrap, toes matching the piping on her dress - attention to detail! - her thin, perfectly-accessorized belt and bright necklace tying her dress to her wrap, and those shoes - the sky reflecting from them, airy and light - she's a top fashion statement from head to toe.
So chic and lovely. But how does she mount a diamond-frame bike in that dress?
I have a diamond frame and ride in skirts/dresses all of the time. I think if the seat is high enough, it isn't a problem.
