The mother-of-two sat down for a one-on-one interview with "TODAY's" Savannah Guthrie on Monday, where she opened up about her fashion empire and upcoming wedding.
When it comes to Jess' success in the world of fashion, she says it's really comes down to her own experience finding the right looks for her body.
"I have been every size there is," she said to Guthrie. "So, I know how to dress every body type!"
The blonde beauty also revealed that she can relate to "every woman out there" and she tries to keep her line accessible to the average shopper.
"You know, we all need pieces in our wardrobe that are fashionable—but accessible, wearable, you know, and affordable," she explained. "I think that that's really what has made the brand such a success."
We can also expect Simpson's big day to be pretty special. Jess said that when she and Eric Johnson tie the knot this summer, their wedding will "definitely be extravagant," adding, "I don't' do things small!"
They're reportedly going to say "I do" over 4th of July weekend.
The former pop star also said that she loves being a mom to her daughter Maxwell, 2, and son Ace, 11-months.
"We get up with the kids. We do breakfast. I'm always with my loving fiancé who I adore more than anything," she said, "and, well, of course, my kids. They're all equal!"
Well, we're sure the 33-year-old will make one beautiful bride! What do you think about Jessica's candid comments? Sound off below and check out even more stars who've dropped weight in the gallery!
