Everybody's wearing... White Shirts

If someone told me at the start of this season that the one item I'd need was a white shirt, I would have hibernated in my polar bear PJ's with the new box set of Gossip Girl, and no-one would have heard from me till there was blossom on the trees.

In case you hadn't already guessed, I find a white shirt somewhat unremarkable. Yet, styled right, this item will be the most coveted item in this Winter's wardrobe.

Celebs are lining up left, right and centre for a piece of the shirt action. Gwyneth Paltrow tucked her silk shirt into black tailored shorts and teamed it with a metallic clutch, understated black courts and a long pendent necklace. This outfit is effortless sophistication at its best.

Leighton Meester gets double fashion points - pairing her shirt with the season's cargo trousers. Like Leighton, leave a few buttons undone and go for short or rolled up sleeves for day time wear. Add a big bag and statement heels in a muted tone to sex up the look.

A new trend doesn't really exist until Sienna's worn it. Miss Miller modernises the classic shirt and trouser office ensemble, with a military shirt. Gold buttons galore and sharp shoulders glam up the dark trousers. Not one to shy away from attention, Sienna spices things up with a 60s inspired, stack heeled platform. What a beaut!

Topshop have some gorgeous takes and cater for all price bands. Follow in Sienna's footsteps with the Gold Button Military Shirt, £38 or try the Side Tuck Short Sleeve Blouse, £38 to re-create casual chic a la Leighton.

If, like me, you're not quite sure about the white shirt, opt for a patterned or coloured blouse - but remember this look is about quiet sophistication, the cut and fabric is eye-catching enough, a loud print is not needed.

Warehouse have a beautiful navy Swallow Print Blouse, £55. Alternatively, Reiss has some exquisite lace blouses and military shirts ranging from a dove grey to a fuscia pink, starting at £79.

It's time to get hot under the collar!
