Kelly Osbourne, Peaches Geldof and Ellie Goulding make for an all-star front row at Charlotte Ronson's vintage-inspired show

Charlotte Ronson's show was the big celebrity draw last night, with guests including Kelly Osbourne, Mandy Moore, Ellie Goulding, Rose McGowan, Peaches Geldof and LeAnn Rimes lining the front row.
The designer sister of Mark and Sam stayed true to form with a vintage-inspired collection that paid homage to the Twenties, Thirties and Forties.
Loose drop-waist dresses, which are proving to be a Fashion Week theme already, came in sunset hues, while delicate pastel floral prints adorned slinky slips and midi skirts.

Summer knits had shirt-style collars and colourful zig-zag stripes, lending a grungy look when layered with chiffon slips and tailored shorts.
It was the star-studded front row that gave this show the X-factor though - probably one of the most celebrity-heavy at New York Fashion Week so far.
The designer's twin sister Sam was DJ for the event, while Peaches Geldof, who was seen with arms slung around boyfriend Thomas Cohen throughout, and Kelly Osbourne, who wore curious white gloves with her grey frock, rallied in support.

Mandy Moore, LeAnn Rimes and Rose McGowan were all dressed to impress in rather formal looks, while Nicky Hilton, Louise Roe and Ellie Goulding went for Downtown looks more in keeping with Ronson's signature aesthetic.
