But that's all about to change.
In the video, Robbins picks out two bikinis to wear to the beach for the first time in an effort to feel more confident about her body and to learn to love herself for who she truly is.
"I want to do this 'cause I see other women [who are] bigger than me wearing them and I'm like 'you go girl.' But if I put it on I'm like 'no girl.' And that's what pisses me off — is that I would tell someone else that they could wear this, but when it comes to me I'd be like 'no.' "
With that, Robbins sports her Ashley Graham black bikini, filming and reflecting on her experience from the moment she touches the sand.
"The moment that I started feeling most comfortable was kind of when I just let myself just be like 'whatever, you're here, you're at the beach, in this bikini, just rock it.' "
And that she did.
Afterwards, Robbins posted photos to her Instagram account, receiving a ton of positive feedback from the social community.
She captioned, "This is me, in a bikini, and I fucking love it."
"Honestly you make me want to get my bikini out for the first time, being plus size and having hate sucks so thanks for being a ray of sunshine xx," one Instagrammer commented on Robbins' post.
