Lydia, who quit TOWIE last year to focus on her fashion career, held the party to mark the opening of Bella Sorella's latest store, located just off Carnaby Street in London.
Posing for the cameras, Lydia stunned in a pretty off-the-shoulder cream lace dress, featuring little feminine bows on the neckline.
Lydia teamed her summer frock with a simple pair of cream and black sling-back heels and a beaded flower head dress, which complemented her new brunette hair perfectly.
Not only was Lydia joined at the party by her family - including mum and former TOWIE co-star Debbie Douglas - her showbiz pal, Denise Van Outen, was also there and turned heads in a stylish monochrome dress.
Denise added a pop of colour to her outfit with a pair of red shoes and matching pout. While at the event, she tweeted: "With my lovely friend @LydiaRoseBright launching her pop up shop tour of @bellasorella251 Well done Lyds xxx"
Late last night, Lydia reflected on her bash and thanked her family and friends for their support.
"Nights like tonight make me realise how lucky I am. I love all my friends and family #bellasorellatourlaunch," she tweeted. Congrats!
