The reality TV star was pictured arriving at Mahiki nightclub in the capital and instantly stood out from the crowd in her flattering choice of outfit.
She teamed a high-neck white cropped top with a matching white skirt and added a splash of colour with a pair of bright cobalt blue heels.
Lucy also carried a black coat just in case she got a bit too chilly and left her make-up simple, aside from the popping pink colour she wore on her lips.
The evening marked Mahiki's decision to ban fur from being worn in their nightclub and party guests were given "No Fur" badges at the door.
Earlier yesterday afternoon, Lucy was spotted having lunch in Soho, for which she rocked an on-trend miniskirt.
In fact, the fashion conscious Chelsea star has been out and about quite a lot this month, especially since it was her birthday last week.
Last Thursday (20 February), Lucy celebrated her 23rd birthday and got together with her pals and MIC co-stars including ex-boyfriend Spencer Matthews.
One person who appeared to be missing from the proceedings though was BFF Binky Felstead, who is currently on holiday in New York with her mum and sister.
And it's obvious that Lucy is missing her partner in crime, as she tweeted this morning: "Come home already @BinkyFelstead xxx"
