Danielle's new clothing store is aptly named DANNI and to celebrate the opening she threw a glitzy party at the premises, which is based in Hornchurch, Essex.
The TOWIE star sizzled in a hot pink pair of shorts and matching jacket, which she teamed with a pretty floral crop top. Perfect for showing off that flat, bronzed tum of hers.
Danielle added a touch of Hollywood glamour by blowdrying her platinum locks into loose curls and she accessorised with the ultimate piece of arm candy - James!
Posing for pictures outside her new business, James was all smiles as he put his arm around Danielle's waist. The star had even been counting down the hours beforehand, tweeting: "Only an hour to go till Danni's boutique press launch!!! @Daniarmstrong88."
Meanwhile, Danielle switched up her style during the night and later changed into a gorgeous pair of monochrome wide-legged trousers and matching kimono.
Again, the budding businesswoman gave photographers a flash of her stomach by wearing a white crop top and she completed this summery look with a simple pair of tan wedges.
The evening - which was also attended by Jasmin Walia, Dan Osborne, Grace Andrews and Georgia Kousoulou - was a great success and Danielle later took to Twitter to thank everyone for their support.
"Had the best night for press launch of the opening of my new Boutqiue DANNI! Have got amazing family, friends and boyfriend #LuckyGirl," she tweeted.
Aww, congrats Danielle!
