Rebecca Adlington goes braless as she dares to bare in frontless dress

The former British competitive swimmer looked stunning as she donned a glamorous black dress.

Rebecca Adlington swimming fans would hardly recognise the 28-year-old as she swapped her cozzie for the floor-length gown.

The blonde got daring as she went totally braless under the sophisticated number.

This was even more brave, considering the dress was slashed right down to her navel.

In this cold December weather too, no less.

The mum-of-one teamed her chic dress with a dainty gold necklace, just above her cleavage line.

She also clinched her waist in with a small belt, meanwhile she accessorised with a matching clutch bag.

Rebecca's makeup was also simple but beautiful, with fluttery lashes and a splash of lipgloss.

Her hair, meanwhile, was coiffed into a sleek half-up hairstyle.

Rebecca's nails were also coated in a a statement red shade.

The sports star was at The Sun Military Awards, which honours members of the British armed forces and civilians involved with the forces.

Also at the event was Loose Women's Andrea McLean, 48, who wowed in a slinky little black dress.

Former Hollyoaks cast member Jorgie Porter, 29, also looked stunning in a sparkly silver minidress.
