A couple of years ago Briony Gorton was working in a shop in Burnley, Lancashire, while studying for a degree.
Now she has her own house, drives a Range Rover and is on track to make her first million at the age of 25.
And it all started with Sh13, 000.
That's how much the Manchester Metropolitan University student spent on fabrics for her first swimwear range.
She took the material, bought in a local shop, to a family friend who was also a seamstress to turn her designs into reality - then set up a website selling them online.
"I was working part time at Pandora and was at university when I realised that one day I wanted to become my own boss," she told MailOnline.
"I used to sit in lectures thinking I was being taught how to work for somebody else - and that wasn't what I wanted."
It's fair to say it worked - with the 23-year-old modelling the range herself and promoting them on social media.
"I'll never forget my first sale. It was the day after I listed my first design. I couldn't believe that not only did other people like what I'd designed, but that they actually wanted to wear them on their holidays," Briony said.
When she started she had around 4,000 followers on Instagram, and the response was incredible.
Inside six months she's launched her website - talliahroseuk.com - and had a Sh13 million business.
Now she has 40 times that number, sells hundreds of clothes a week and even models for other people.
She's even moved into her own premises, photo studio attached, has a new house, a car and hundreds of sales a week.
She's on track to be a shillings centimillionaire by 25.

But the success wasn't without problems - people started taking her designs and selling cut price copies made in China.
"I was devastated and had no idea what to do or how to protect my brand," Briony said.
"I turned to legal advice but was told as I hadn't patented my designs that I didn't have a leg to stand on - basically I could do nothing."
But the setback didn't stop her - with Briony moving from swimwear to clothing and footwear as well as using her Instagram account to model for other brands.
"When I was promoting my own brand, I was spotted and picked up by some big clothing companies who asked me to do some paid promotions, which I quickly turned into another business," she said.
Perhaps what's making her happiest, is what her success means for other people - she even bought her mum a car.
"Her reaction was PRICELESS and I’m so happy I can now start to give back to my amazing mum," she wrote on Instagram.
Briony added: "I have the perfect platform to advertise my brand and boost my sales, but I also try my best to promote girl boss vibes on my Instagram and encourage people, especially young girls, to chase their dreams. There is no limit to success!"
