Suki Waterhouse and Cara Delevingne have been inseparable this week, going out three nights in a row. On Wednesday night they hit the Chiltern Firehouse - the It restaurant of 2014, don't cha know. The question is did Cara go a crop too far? She wore leather trousers and a striped jacket with a micro crop top. Jessica Biel meanwhile has shown us how to do crop tops the grown up way, pairing hers with high waisted white trousers and a glossy blow dry.
On Tuesday evening it was the official launch of the Kate Moss for Topshop collection and she rounded up some of the hottest it Brits to celebrate - dressed head to toe in her collection, obvs. Sienna Miller, Cara Delevingne, Suki Waterhouse and Naomi Campbell attended the Kate Moss for Toppers dinner. Kate Moss changed out of her tuxedo into a silver maxi with a fringe tiered metallic bolero jacket. Naomi went matchy matchy with Mossy in a beaded fringed cocktail dress.
Just when you think Emma Stone couldn't get any more stylish - there she is, monopolising our best dressed list. Again. We love the black pleated Gucci dress with open sides and a leather collar which she wore on Jimmy Fallon on Monday evening. She also championed the collar over the weekend in a red Valentino mini dress with a statement embellished collar.
This weekend Gia Coppola hit the red carpet at the Tribeca Film Festival in a sleek white Saint Laurent tuxedo with a white sheer shirt. Keira Knightley was back in her signature Chanel silhouette - a waist-cinching dress with layered skirt - at the Begin Again premiere which closed the Tribeca Film Festival.
Speaking of Chanel, the house's other ambassador Diane Kruger was spotted out and about in Los Angeles with the bag of the moment, the Chanel backpack, paired with a seafoam dress. Sarah Jessica Parker is back on our best dressed list (again) in a Giles floral dress, while Rita Ora opted for a slinky DKNY LBD to the Paper Magazine 'Beautiful People' party over in New York.
Rihanna spent the weekend at the basketball court, as she went to see the Toronto Raptors vs Brooklyn Nets playoff game in New York. RiRi looked flawless in a Christopher Kane camo-print crop top and matching high-waisted pleated skirt. She paired it with a varsity bomber jacket by Étoile Isabel Marant and red Nikes. While we're on the topic of basketballs, Rita Ora got in the spirit by dressing as a b-ball in an orange Jeremy Scott jacket.
