London, May 30 - A new "diet in a swimsuit" helps women drop a dress size without them having to sweat out in the gym.

A blessing in disguise, the 30-pound Bhs cozzie is made of a specially developed material that tucks in tummies and boosts boobs.

Bhs scientists spent a year developing the swimsuits, which have a clever super-stretchy inner mesh of elastane and nylon to squeeze and flatten bulges into shape, reports The News of the World.

An outer layer, also of elastane, smoothes the silhouette and a padded support hoists boobs to give a sexy cleavage.

A Bhs spokesman added: "We realized ladies were fretting about showing their bodies. The collection was launched to create an immediate fix to their predicament." (ANI)
