Katy B is one of those celebrities that can get a look so right or so wrong and she has had her fair share of fashion disasters. (remember that telephone box dress?) But we’re glad to see that she’s learnt from her mistakes as she walked the red carpet at the premiere of new British film Fast Girls on Thursday in Leicester Square.

The On a Mission singer kept it casual with a white patterned t-shirt and super tight mottled jeggings. To make sure she didn’t look like she was just popping down to the shops, Katy added a leather jacket, maxi clutch and a pair of  gorgeous strappy sandals.

We love the edgy touch of the blue nails and her wavy hair which gives her that hollywood look and we’re hoping this style upgrade from Katy B isn’t a one-off.
