THERE is one item found in every wardrobe which you can throw on with almost anything from trousers, leggings and skinny jeans to shirts and skirts.

The humble T-shirt — equally at home on its own or as a base layer under a cardigan or blazer — is the ultimate in versatility.

But what's the best way to wear it?

To find out, the Post teamed up with that high street mecca of cut-price designer labels, TK Maxx, Penclawdd-based make-up artist Sascha Martini and hairdresser Alex Smith to give three readers a fashion makeover.

Celebrity stylist Hannah Sandling, who has styled the likes of A-listers such as Sienna Miller, Dita Von Tesse and Carmen Electra, worked her magic at the city's Parc Morfa branch to show three readers different ways to wear this year's Sport Relief T-shirt designed by the Beckham family.

Eat your heart out, Gok Wan!

Victoria and David, along with their boys, have created a series of one-off designs with the hope of inspiring the nation to rise to the challenge for Sport Relief 2010.

Each T-shirt features The Beckhams for Sport Relief logo, a combination of the footprints of each family member and all net profits from sales will go towards helping people living unimaginably tough lives across the UK and the world's poorest countries.

After rushing around the store tracking down outfits for our three makeover winners, Hannah said: "T-shirts are the most versatile item you can get — you can dress them up or down, they can be sporty, they look great with high heels. The Sport Relief T-shirt has been designed by the Beckhams for a good cause so it means you're doing something good for charity and also buying a little slice of celebrity-dom.

"TK Maxx is great if you're on a shoestring, it's a real treasure trove where you can find something for any occasion, from a ball to a lunch date to a skiing holiday."

The Sports Relief T-shirts are on sale in-store and online at Sainsbury's, TK Maxx and www.sportrelief.com for £14.99.
