Luminous Silk Foundation, £28 by Giorgio Armani. For stockists call the Giorgio Armani cosmetics counter at Selfridges - 020 7318 2486
Kimberly has a great complexion and rather than covering this with a heavy base, she just enhances her asset with this Giorgio Armani foundation, which gives the skin a radiance and avoids the 'caked on' look (plus it looks fabulous when Kimberly is in front of the camera).

Miss Marissa, around £30 by Ebba at Lucky Scent
Instead of spritzing herself in an overly expensive fragrance, Kimberly's signature fragrance is the fresh, light and summery Miss Marisa by Ebba. Although it's only available in the US we found the Lucky Scent site which ships the fragrance over here.

Fine hair shampoo, £5.99 by James Brown London
Kimberly's hair is quite fine and although her elfin crop has given it more body, she uses James Brown's shampoo and conditioner for fine hair which gives it maximum body. Kim also tells us she is just a wash and go girl (we're not sure we believe her!) and just uses a little styling gum before she leaves the house.

Lipstick in Hue, £11 by Mac
Kimberley swears by her Mac lipstick in Hue, it's pale enough to slick on as easily as a gloss but is far more on trend.

Rosebud salve, £6.95 by Smith's at HQHair
This multi-purpose salve can be used on lips and dry patches, Kimberley loves to keep it on her at all times especially when she's travelling.
It was the hair cut that did it. In 2008, Kimberly Stewart's elfin crop transformed her from L.A. party girl into serious fashion and beauty maven overnight. Kimberly spends much of her time in London hanging out with scenesters like Peaches Geldof and Kelly Osbourne, so no doubt about it, her look had to evolve.
Gone is the laid back, long beachy hair and skimpy, jersey dresses (typical summer fare in Hollywood), replaced by a more serious and directional style (note her new penchant for head to toe edgy black) and a more interesting beauty regime, which suits her new London lifestyle.
Her look is still simple with a cool, rock and roll edge - luminous skin, 60s eye liner, nude lips, mussed-up hair and classic red nails by Ciate, of course, she's the face of the nail colour range after all.
