That shade of blue looks fantastic on Serena.
I didn't love Serena's Paris outfits though - hated the one above, and the one with the blue harem pants and gold blazer with the massive bags. She looks like those stereotypical 'Loud American Tourists' (who I know, don't represent all tourists, or all Americans) who are dressed up in blingy designer stuff, ordering the sales assistants around on Avenue Montaigne/Rue du Faubourg Saint-Honoré...
I was actually hoping the Paris fashion - especially for Clemence, would be a bit more understated. You know, some cute tailored trousers, silk blouses, mini Kelly bags slung over the shoulder with cool flat Isabel Marant type ankle boots. I guess what Eric Daman has done though will work better on TV.
