The body confident 20-something girl has a huge fan following as she promotes a positive attitude towards being plus sized and zero tolerance to body shamers.
In an Instagram post, Callie wrote: "I never dreamed I would wear a dress like this, I used to think that I would never get married until I was thin."
In a series of stunning photographs Callie, who is originally from Wales but now lives in London, shares her big day with new hubby Dan.
Callie wore a beautiful dress with a slight sparkle made by David's Bridal, a shop in Stratford.
"The champagne colour that perfectly complemented my olive skin, the way it fell over my hips and followed the curves of my figure. It was just magical." Callie said on her Instagram.
In a sentence that nearly brought a tear to our eyes, Callie confessed her journey with body insecurity, and finding someone who loves her no matter what.
"As you grow older and you surround yourself with the right people, you begin to realise that what you look like doesn't really matter to those that love you.
"Dan has loved me at all different sizes and on the day of the wedding when I walked into the room he turned and teared as I walked towards him, he looked at me like I was magic."
Giving advice to fellow brides out there, plus sized or not, Callie has some incredibly heart-warming advice: "Do not feel you have to change yourself or your size to be happy on your wedding day, your partner loves you for who you are, not just what you look like.
"You are deserving of happiness no matter what your size, and you will still be the most beautiful person in the room next to your love because you will be glowing with the love you have for each other."
"The happy ending is for everyone so please, please let yourself have it."
