You all know how much I love the smiling Olsen. She is my favourite Olsen. Yes, I have a favourite Olsen. Lots of people do. Mine just happens to be the young 'un, Elizabeth Olsen. And this week she appeared on Jimmy Fallon's show to promote her new movie. I have no idea what it is called, but I am sure that it is good.

She wore an Acne white shirt dress for the appearance. And I totally love it. This is going to be a major trend this summer and I want one STAT. The fact that she wore it with my absolute worst shoes — despite that they are by Marni — cannot dull my ardour for the dress.

She later popped on a leather jacket to keep out the chill on her way to and from the studio. I think I like it even better in this arrangement. Really a fantastic ensemble. No?
