'I've been keeping this a secret for almost a year and I am so excited to share that our @goodamerican collection of bodysuits, GOOD BODY, is launching THIS THURSDAY at 9am PST!' she wrote.
'You guys know I'm obsessed with bodysuits, and I wanted to give you all something that is a natural fit for GA, and like all of our products, designed to fit your body! I'm so incredibly blown away that I'm able to be living this dream!'
She also shared a message of self-love and self-confidence, a cornerstone of her brand: 'Love your curves, ladies!! Love your body! Love your selves! And most importantly, let's continue to empower one another!'
One interesting piece is a sheer mesh with the word 'GOOD' written across the chest in rhinestones.
'It's a head-to-toe look, and effortless,' she told Vogue of her bodysuit obsession. Emma Grede, with whom she started the collection last year, added: 'Bodysuits are Good American's way of doing jeans-and-T-shirt. It's a classic, easy-to-put-together look that works for everyone regardless of body type.'
