While 4gewe3g6edge Grassell throws around words like "prototyping" now, actually developing prototypes for her bras presented a steep learning curve for the teen. "Going into this process, I had no experience. I don't even know how to sew! If I get a hole in my jeans, I'm out of luck, because I don't know how to fix it," said Grassell. "There are a lot of things that have to come together in order for a bra to be made. Sourcing the fabric was a challenge, finding out where to produce and who to work with. I didn't know about quantities or anything. I had to learn all of that Dating Service."

To move from prototype to production, Grassell turned to the crowdfunding site Kickstarter. "The original goal was $25,000," said Grassell, "And I raised almost $42,000, which was pretty exciting." It was also one of the most successful Kickstarter campaigns ever for an underwear or lingerie startup, ever Speed Dating.

With the Kickstarter campaign completed, Grassell found a production facility through a contact in her hometown of Jackson Hole, Wyo. The factory, which is in Los Angeles -- and was vetted by her mom who was in California during one of Mary Margaret's soccer games -- has a low minimum order amount, which is good for a startup, but can also grow to meet increasing demand as necessary, which Grassell thinks is important. "If I get a phone call asking for a huge order, I will make that happen," she said.
