The reality star showcased her incredible figure in the revealing ensemble, appearing to go underwear-free in the thigh-high split number.

Dorothy's chest almost spilled out of the one-shoulder dress, which sparkled with an array of silver sequins.

Dorothy finished off her look with a white Hermes Birkin bag, one of her large collection of the iconic piece.

The socialite added height to her frame with strappy heeled sandals, while tying her sleek blonde tresses back into a high ponytail.

'It's very easy and very fun to be single in LA.

'But one of the problems is that everyone in LA is single, so you don't feel that single, if that makes sense?' Dorothy told News Corp Australia.

'There's always something going on, somewhere to go out. You don't really feel the void until, like, Sunday, when you have the morning-after hangover.

'And you're like, 'I wish I had someone here to order Postmates with me.''
