The former TOWIE star, 23, was excited to meet and greet fans in Manchester on Saturday (14 June) and dressed to kill for the occasion.
But instead of wearing an outfit from her own shop, Minnie's Boutique, or an expensive designer number, Sam wore a simple but elegant white dress from M&S.
Tweeting her excitement about her day at the city's Trafford Centre, she wrote: "Wearing my speziale peruna dress from @marksandspencer."
The sleeveless pencil dress fitted Sam's petite frame perfectly and showed off her natural-looking tan. And we love her silver heels!
Wearing her blonde locks loose but elegantly curled, Sam could have been mistaken for a Hollywood screen siren.
After promoting her new fragrance La Bella all afternoon, Sam later thanked fans for their support.
She tweeted: "1st signing. Had such a lovely day, everyone who came to meet me was kind & polite. Glad u all like your new fragrances. See u again soon xx."
On 5 July, Sam will be heading to Glasgow to continue her La Bella signings, followed later by Newcastle, Cardiff and Liverpool.
It's great to see Sam so happy at the moment. Not only is she in great shape after her diagnosis of Crohn's Disease earlier this year, the former CBB star is back in the arms of Joey Essex and her career is skyrocketing.
The reality TV star also seems to have friends in high places... She was recently pictured cosying up to A-lister Liz Hurley!
