This dress looks a little bit like lingerie. We're not even gong to deny it. Sometimes, though, we like a little bit of "underwear-as-outerwear", and when the "underwear" in question (Note: It's not actually underwear, you understand. It really is a dress.) is as pretty as this one, we're totally on board with it.
Net-a-Porter suggest wearing it with a denim jacket over the top: not a bad idea, it'll provide a nice contrast, and help stop you looking like you're out in your nightie.
It's £345 and available from NET-A-PORTER .
