See who looked good out and about this week.

Olivia Palermo nailed two of the season’s biggest trends, all black and fringing, at the CFDA Fashion Awards in New York this week.

Lupita Nyong’o has got dressing for the polo down to a T: sun hat, wedges (so not to sink into the grass) and a summer frock, all perfectly coordinated.

Alexa Chung never really gets it wrong, but we thought her outfit at the Royal Academy Summer Exhibition Preview Party in London was particularly on form.

Obviously most people won’t be rushing to replicate Rihanna’s CFDA Fashion Awards look, but we have to give the style icon credit for what she does best: push the boundaries.

Ashley and Mary-Kate Olsen work kimono dressing perfectly at the CFDA Fashion Awards.
