WITH wads of cash and stylists on speed-dial, it's no wonder our favourite stars look fab most of the time.

But all the money in the world can't save celebs from the occasional unflattering frock-up.

Lily Allen, for instance, should have everything to Smile about, as she looks ultra slim in a gorgeous red dress this June.

But compare this to her punky look at the O2 Wireless Festival in July and you could be wondering if this is the same girl.

Leopard print leggings do nothing for Lilly’s legs, and the baggy tee-shirt leaves her slim upper half, shapeless.

"As a pear shape Lily Allen should know that teaming leggings with a short vest is the quickest way to add unwanted pounds," explains Toni Jones, Sun Online's Fashion Editor

"The red Vivienne Westwood dress is a masterclass in dressing for your shape though.

"The British desiger is famous for her corseted frocks that shrink the waist and push up the chest.

"No-one's looking at Lily's thighs in THAT dress."
