Holly, 21, first found fame on the MTV reality show in 2011 and even she cannot believe how much her looks have changed since then.
The star, who is a healthy size 10, now works out with a personal trainer two to three times a week and has gradually dropped 3st in weight. Her style has also had a makeover.
Unveiling her new clothing line with The Fashion Bible, Holly tells Reveal: "It's scary when people tweet me old photos of myself from series 1 of Geordie Shore.
"I always have to double take to check that it is me. I've got quite big facial features, and as I've grown as a woman, I think I've grown into my own face and body too.
"I'm far from body confident, but I've learned to accept the way I look and I also accept that I'll never be a 'skinny girl'."
Holly adds: "It's more acceptable now than ever to be curvy, with the likes of Kim Kardashian and Nicki Minaj showing how curves are sexy, and I'd much rather look like them then be a stick thin rake!"
Last month, Holly's Geordie Shore co-star Vicky Pattinson unveiled her bikini body following an intense diet and fitness regime.
Although she is happy having curves, Holly does admit she still feels a little bit pressured to follow in Vicky's footsteps.
"A question I'm asked more and more is whether I feel more pressure to look slim because of how unbelievable Vicky looks now, and the truth is sometimes.
"Vicky looks incredible, beyond incredible in fact, and stood next to her, it's clear we both look different.
"I do work hard to maintain my body, I work with a personal trainer 2/3 times a week and we train really hard together.
"But, even if I worked out everyday, I could never achieve a body shape like Vicky has done."
We think you look great, Holly!
