Turning heads in the floor length dress, Heather showed off a hint of leg through semi-sheer inserts along the seem. And twirling for pictures, she flashed the flesh with a backless insert fastened at the neck.

Heather's dress, with Japanese lily flourishes, was tapered in around the waist before billowing out to skim the floor.

Letting her short blonde tresses fall to her shoulders, Heather wore a smattering of light makeup to highlight her natural good looks.
