London: For women who dread revealing their lumps, bumps and less-than-perfect figures in swim-wears, a new swimsuit could be the perfect solution.

The 45-pound "slimsuit" or "diet in a swimsuit",  dubbed Spanx for the beach, from Debenhams has been created after its poll of British women showed 92 percent fear how they look in swimwear.

Despite more than half saying they had gone on a diet in an attempt to look good, they still found their costumes and bikinis ill-fitting and unflattering.

The design's secret is the illusion of instant weight-loss, helping to shape the body in the same way as Spanx control tights and lingerie.

"The challenge was to use data to create a suit that accentuates the good bits, and smooths the lumpy bits without making women feel like they're wrapped in cling-film," the Daily Express quoted Debenhams swimwear buyer Sasha Nagalingham as saying.

The suit's inner layer is made from a specially-designed heavier gauge lining fabric which does the "miracle work", while the outer layer is a slinky micro-fibre.

Low-rise legs ensure no bulges and a smooth curve in the hip. Moulded bust supports lift and separate in a similar way to a bra. It is sized by cup fitting as well as dress to make a perfect fit.

Extra strength through the waist panel creates an cinching effect and a control panel simultaneously flattens the tummy.
