"I tell my girls to forget every fashion rule,” says Gregg, 29, whose fourth Swim Sexy collection with SwimsuitsForAll goes on sale Tuesday.

"The message that [larger ladies] get when it comes to fashion is constantly what not to wear: If you’ve got big hips, minimize them by wearing black; don’t wear this cut because it makes you look bigger,” she explains.

"Break out of that! Play with those trends you love. You can rock a lot of things you didn’t think you could.”

Gregg went viral in May 2012 after posting a photo gallery of 31 full-figured women in titillating two-piece suits that showcased their curves rather than hiding them.

She’s since become the "Queen of the Bikini” with her swimwear that is structured enough to support up to a size H bust (so that no woman’s cup runneth over) - while also being flirty and fashion-forward enough to turn heads.

"I definitely make statement swimwear that my girls usually cann’t find anywhere else in their size,” says Gregg. "We have a few cool options [generally] but you konw there’s not a lot out there.”

The beauty is in the details, such as flattering high waistlines that are on-trend right now, underwire bras to keep "the girls” in place, and illusion mesh paneling on some suits to control how much flesh a lady wants to flash.

Gregg’s new 14-piece collection includes 12 bikini and one-piece styles in flirty flamingo and lips patterns, as well as two coordinating cover ups. They are all priced around $100

Her personal favorites include a lilac bikini printed with black leaves and an athletic racing stipe, as well as a khaki one-piece without underwires that’s suited for smaller busts.

"It’s different from anything I’ve ever done before” she reveals. "I’m always looking to hear what my girls have to say, and this collection is the best one yet.”

She’s encouraged by the strides made for plus-sized shoppers over the past year, including Ashley Nell Tipton winning the last season of "Project Runway,” Forever 21 debuting its first plus-sized activewear line, and plus-sized models like Ashley Graham appearing in Sports Illustrated’s Swimsuit Edition.

But it’s not enough.

"So many girls just want the same shopping experience as their [skinnier] friends, and for some reason, people are either close-minded about designing for us, or they just don’t want to figure out this market,” she says. "They need to step up.”
