The gorgeous sisters were thrilled to take home prizes for their fantastic Minnies Boutique in Essex, while Sam also scooped the award for 'Most Stylish Celebrity'.
And looking at these pictures of her last night, it's no surprise!
The blonde beauty looked stunning as she posed for photographers at London's exclusive DSTRKT club ahead of the glitzy awards show.
Sam, who recently bowed out of TOWIE to focus on other projects, showed off her golden tan and trim tum in a striking outfit. Our favourite part? That amazing handbag!
Meanwhile, her equally gorgeous sister Billie looked fantastic, showcasing her blossoming baby bump in a cute patterned dress from Zara. She kept a protective hand on her bump as she posed for pictures at the awards, which were sponsored by Pro:Voke Touch of Silver.
Sam and Billie were ecstatic that their Minnies Boutique was named 'Best For Celeb Style' and 'Best Boutique', while Sam was named 'Most Stylish Celeb'.
Posing at the end of the night with her awards, Sam said: "Congrats to Minnies and me! Thank you to everyone who voted." Billie added: "Very proud of our @minniesboutique winning 2 awards at the Reveal fashion awards."
A source said: "The Minnies team were thrilled to win! They were making lots of noise as they congratulated each other."
And the girls also got support from fellow TOWIE star Gemma Collins! Our insider said: "When Sam and Billie won, Gemma couldn't have been more excited. She was shouting her congratulations and telling everyone that Sam and Billie are true superstars."
