The former Only Way Is Essex star opened her first Amy Childs' Boutique store, after previously launching a clothing range online.
"It is classy, elegant, we've got chandeliers in there, beautiful wallpaper with all diamonds on it," she told The Sun.
"I'd describe it as sparkly, classy and elegant... just like me. It's a glam boutique."

"My website crashes all the time, and people are always on it, so I thought, 'Why not open a boutique?'
"I'm really excited, really excited, but obviously I'm nervous because I want it all to go to plan.
"I want everyone to be like, 'Oh what a lovely boutique'. As it's my second shop opening, I just want it to run smoothly."
The 22-year-old was joined by a number of celebrities, including Peter Andre, cousin Harry Derbidge, boyfriend David Peters and Lizzie Cundy.
She added: "Dave is coming along, he's been up all night helping me. It's so nice to have your boyfriend helping you out, he's been really good.
"He's actually learnt quite a lot about fashion, designs and I think he knows every single name of my collection now."
Amy Childs also launched her debut perfume range last month.
