Paris Hilton has been parading about in Halloween costumes all week.

But the all-white ensemble she stepped out in on Thursday was easily her headline piece.

The 33-year-old appeared to be dressed up as her $13,000 white miniature Pomeranian puppy Prince Hilton.

Great idea: Paris Hilton appeared to dress up as her $13,000 white miniature Pomeranian puppy Prince Hilton to her Halloween party on Thursday

Imitation is the highest form of flattery: Prince Hilton was no doubt honoured that his mum decided to dress up as him

Naturally, Paris couldn't help but sex up her unique costume idea by wearing a strapless, corset dress.

The frock was particularity short, even by the heiress' standards, but allowed her to show off her fake tanned legs.

Paris' younger sister Nicky may not have given her approval to the look as she recently admitted to DuJour.com that her 'tanning phase' is her biggest style regret.

Accessory queen: Paris completed her cute outfit by wearing a baby blue dog collar, fishnet gloves and fluffy white ears

That's hot: The hotel heiress proudly showed off her long, toned legs in the very short mini dress

'I used to live in Los Angeles around the corner from a tanning salon, and needless to say I frequented it quite often,' she confessed.

'But, in my defence, everyone was orange back then!'

Despite her sibling's comments, Paris didn't seem too concerned about her orange tinted skin as she posed in a baby blue dog collar and quirky sunglasses a la Prince Hilton.

The heiress recently opened up to MailOnline about her other six pooches feeling jealous over the attention Prince is getting.

What would Nicky say? Paris' younger sister recently admitted that her 'tanning phase' is her biggest ever style regret from over the years

Who cares? Despite what her sister may think of her tan, Paris was more than happy to pose for fans at her Halloween Party at 1OAK in West Hollywood

'Peter Pan is especially upset because I used to take him everywhere. He was the top dog.

'So there are some sad feelings there. Prince is just the new one, so he is getting the most attention.

'I think Peter Pan might want some more trips out, so I will work that in.'

Paris' decision to dress up as Prince rather Peter at her Halloween Party at 1OAK in West Hollywood, probably didn't sit too well with the former top pooch.

However after she had finished DJing for the famous faces at the club, which included Dorothy Wang, Shei Phan and Sean Stewart, she no doubt went home and paid the pup lots of attention.
