Magic Underwear - known as "Solution Lingerie" in the States - really has changed the shape of womankind in the past few years. It smooths a silhouette, eliminates bulge and is a great confidence booster too. M&S has plenty of options - from all-in-ones to long-line knickers (we're not talking sexy here, but that's the price you have to pay).

Talking of price, they're not cheap either - around £30 for a body. You should also try Spanx, the original magic knicker - and there's a new line from Maidenform called Flexees, which promises to shape your waist. The best possible place to buy all of these items is Fenwick in Bond Street. The store has expert fitters and a huge range, and you'll come out half the woman you were!
