The Only Way Is Essex beauty is fronting the Alexis Smith Lingerie range after getting a boob job earlier this year.
And she showed off her curves in racy pink, white and black underwear.
Viewers of the ITV2 show saw Jessica, 25, go under the knife to boost her bust from a 32C to a 32DD in the second series.
She had cosmetic surgery despite her brother Mark, 24, saying he didn't want to deal with men staring at her chest.
Jessica said: "I am delighted to be fronting this stunning range of bras crafted especially for girls like me who have undergone breast augmentation.
"The unique design of Alexis Smith lingerie means not only that I look and feel great wearing it but also the pure silk material means they are unbelievably comfortable for both augmented and natural breasts."
Creator Alexis Smith said she created the collection after finding that she couldn't buy the bras she wanted following her boob job.
Last month Jessica enjoyed flashing her new figure in a number of bikinis.
She joined the rest of the TOWIE gang in Marbella, where she showed off her curves while soaking up the sunshine.
