Holly, 21, has got a fun evening planned tomorrow at London's Cafe de Paris and she has been busy selecting the perfect dress for the occasion.
Standing in front of the mirror at home, Holly tried on both a sexy LBD and a snakeskin number with thin straps, a plunging neckline - and a bargain price tag to boot!
The black and white frock is from Lasula Boutique and is priced at just £16!
But while Holly clearly loves the dress, she's decided to show off that tiny waist of hers in the more-fitted black number tomorrow night (3 October).
Commenting on a snap of herself wearing the LBD, she said: "Love my new @houseofcb dress for Cafe De Paris on Saturday."
Since rising to fame on MTV's Geordie Shore three years ago, Holly has undergone a dramatic transformation. As well as ditching the brightly coloured hair for brunette tresses, Holly has also slimmed down from a size 16 to a size 10.
The star lost weight by cutting back on junk food and exercising regularly. In fact, she barely recognises herself!
Recently, Holly admitted to Reveal: "It's scary when people tweet me old photos of myself from series 1 of Geordie Shore. I always have to double take to check that it is me!"
Meanwhile, Holly just has released her own autobiography Not Quite A Geordie and in it she opens up about her bully ordeal as a teenager.
The star's book can be picked up in WH Smith stores or downloaded to iPhone or iPad here!
