As AW11 is upon us, celebrities on and off the red carpet continue to cement the trends we’ll all be wearing for the next three months. Johanna Payton picks her favourite star styles – and shows you how to pinch them.

Now “Hermione” is behind her, Harry Potter actress Emma Watson can press ahead with her one woman mission to become the world’s most adored fashion icon. With her (slightly darker than usual) elfin haircut, and keen eye for a beautiful designer frock, it’s no wonder she is such a universal style crush. Steal her style with a flattering cocktail dress teamed with sleek and simple accessories – all in jet black.

To steal the style I suggest this cotton-poplin ruffle cocktail dress by Juicy Couture, £220 at www.net-a-porter.com. Pair that with this shiny black belt by Moschino Cheap and Chic, £74.87 at www.fashionista-outlet.com. Add some black patent court shoes, £25 at www.desireclothing.co.uk and finally finish it off with some black gem drop earrings, £95 at www.astleyclarke.com.
