Ultimo Mega Boost bra goes on sale

A bra that lets women have a modest bust by day, and killer cleavage by night has gone on sale.

The Ultimo Mega Boost Day to Night bra can boost a women’s bust by up to two cup sizes by the simple addition of two specially-moulded silicone pouches.

It has been designed to allow women to alter their assets for a night out without needing to change bras. By removing the implants, the wearer can sport a modest look suitable for the office. After-hours, a simple trip to the bathroom to insert the boosters creates a sexy evening look.

Ultimo's Michelle Mone said: “The best thing about the new Mega Boost Day to Night Bra is that you can change your cleavage on a whim and it's completely hassle free. It's the perfect solution if you're heading off after work and don't have time to go home and change.”

Unlike other “chicken fillets”, the inserts in the bra mould to the skin to create a “natural, authentic rounded shape”.

They are also said to be the first silicone boosters that come in their own bra, rather than being sold separately.

The Ultimo Mega Boost Day to Night bra comes in three colours and costs ?24.
