Busty or not, we've all experienced the gape.

You know, that spot across your chest where your blouse will pucker and gape, revealing your bra or, worse, actual flesh? There's really nothing more distressing than having serious conversation only to realize that your private bits have been on display for all to see.

Rochelle Behrens was a young woman working in politics in Washington, D.C., who literally wore a button-front shirt to work every day. And after grappling with safety pins day after day to keep her shirt from gaping, she vowed to build a better button-front shirt, and the Shirt was born.

The Shirt by Rochelle Behrens has a double-layer placket that hides two strategically placed buttons. It is made in a cotton blend that stretches, smoothing out the look no matter what your size. This fit allows you to wear your real size or one smaller because it will fit -- you don't have to size up to make the garment fit your bust.

"Why hadn't anyone thought of this sooner?" Behrens asked StyleList. "Maybe it took the perfect storm of my situation. I didn't go to design school, but I knew how to wear a shirt and how to wear it to an office." She added, "It takes someone in the trenches to figure out what's not working and to fix it."

Behrens takes inspiration from Sarah Blakely's success with Spanx. "She took pantyhose that existed, reinvented them and made people realize that they can wear them a different way," Behrens said. "She started with the butt, we're going after cleavage."

The shirt comes in two fits -- regular and skinny -- and nine different colors. It's currently available at Bloomingdale's, Von Maur and online for about $80. There are also two more fashionable styles, which is something Behrens said she will add to the collection each season.

It's so genius even Oprah, who is always on the lookout for what's really functional, chose the Shirt as a "Fashion Must-Have for 2011" in a show that aired last month.
