In the world of fashion, one problem that women often deal with is visible panty lines when wearing tight clothes. Whether it’s leggings, dresses, or skirts, those lines can be uncomfortable and awkward. Even options like thongs or seamless underwear aren’t perfect—they might be uncomfortable, or the lines still show through.
That’s when two best friends, Olivia and Elvira, came up with a brilliant idea. They created Stringies, a brand of invisible panties that stay in place without straps, giving you comfort and a completely smooth look under your clothes.
They brought this idea to Shark Tank, and it caught everyone’s attention.
What is Stringies Underwear?
Stringies is a line of strapless, adhesive panties designed to stick gently to your skin. They don’t roll down or dig in. These panties are:
-
Invisible under clothes
-
Easy to wear
-
Comfortable for all-day use
They are made from bonded materials and were perfected after 60+ design trials. Each pair costs $2 to make and sells for $14, giving the business a great profit margin.
Shark Tank Pitch: What Happened?
Olivia and Elvira entered the Shark Tank asking for $300,000 in exchange for 5% equity, valuing their company at $6 million. They shared their sales story, production cost, and long-term plans.
Here’s a table to show how each Shark responded:
| Shark | Offer | Counteroffer | Deal Accepted? |
|---|---|---|---|
| Daymond John | Out | N/A | No |
| Lori Greiner | Out | N/A | No |
| Kevin O’Leary | $300k for 3% + $1/unit royalty (perpetuity) | $300k for 3% + $0.22/unit royalty | No |
| Mark Cuban | Out | N/A | No |
| Barbara Corcoran | $300k for 10% | $300k for 3% + $0.22/unit royalty (accepted) | Yes |
Barbara loved their energy and potential. Olivia and Elvira countered with a better royalty deal, and Barbara agreed. This meant the company was now valued at $10 million.
Why Did Some Sharks Say No?
Lori Greiner liked the product but felt it wasn’t the right fit for her, especially without a patent.
Daymond John was concerned about scaling and production challenges.
Kevin O’Leary wanted a higher royalty, which Olivia and Elvira didn’t agree to.
Mark Cuban felt he couldn’t add value to this particular product.
But Barbara believed in the idea and sealed the deal.
