Kelly Bensimon, 47, has legs for miles in TINY mini-dress as she steps out in New York

Age is just a number - and Kelly Bensimon proves it.

The 47-year-old reality TV star, model and writer was spotted out in New York on Wednesday wearing a revealing white dress.

She was attending a trunk show for designer Alvin Valley, who had made the pristine white gown.

The former Real Housewives Of New York star stepped out onto the sidewalk to chat with friends and walk her aptly named puppy, Fluffy.

She wore pink stiletto heels and let her copper locks hang freely.

Topping off the look, Kelly wore a variety of accessories including an Hermes bracelet and a few of her self-designed necklaces.

Bensimon's eponymous jewelry brand includes the anchor and owl pendant necklaces she's seen wearing.

Both items run upwards of $200. Her line also features bracelets and star-shaped earring studs.

Also available on her website is a signature line of home fragrances.
