The former TOWIE star showed that casual ripped jeans can still look elegant as she attended the Petits Bisous Boutique anniversary party on the exclusive Kings Road in London on Thursday (13 February).
Lucy teamed her cropped denim with a high-necked white shirt and gorgeous lilac coat for a look that screamed sexy sophistication.
Loving the heels as well, by the way!
Lucy, 22, is celebrating Valentine's Day single this year but looking like this we doubt she'll stay that way for too long - especially if any suitors have seen the picture she tweeted of her Valentine's Day gift to herself!
While browsing the racks at the luxury lingerie store, a couple of sexy items caught her eye. She tweeted a picture of them alongside the caption: "Happy Valentine Eve to me."
The brunette shot to fame on The Only Way Is Essex but chose to leave the hit show last series in order to focus on other business projects including her rapidly expanding Results With Lucy fitness and nutrition brand.
Lucy's brand already has a popular website, Results With Lucy, offering weight loss and weight management tips. Readers can watch videos of Lucy herself working out with her trainer, as well as getting inspiration for healthy eating recipes.
In addition to that, Lucy launched her first ever BootyCamp boot camp this month, which saw her whipping fans into shape across two days at the plush Condover Hall in Shrophshire.
The camp was aimed at people who wanted to tone up and kick bad eating habits all while having fun with exercises including yoga, hula hooping and hiking.
As if that wasn't enough to keep Lucy busy, she also runs two Lucy's Boutique stores and an online shop.
