Olivia Karina and Elvira Tröger didn’t set out to start a fashion brand. They were just frustrated with their underwear. They loved wearing fitted clothes but hated dealing with visible panty lines. Going without underwear wasn’t an option, and the thongs they tried were either uncomfortable or showed through light fabrics. One night, while chatting over drinks, they started joking about how someone needed to invent “invisible underwear.” After throwing around ideas, they realized they might actually be onto something.
Olivia had a background in fashion, working as a model and stylist, while Elvira came from a business and branding background. They knew that if they could find the right fabric and fit, they might solve the problem that so many women faced. They wanted something that felt natural to wear, stayed put, and wouldn’t show through clothes. They started sketching out ideas, imagining a thong that didn’t rely on elastic at the hips but somehow still stayed in place.
They knew they needed a material that would hold without being obvious. After experimenting with different fabrics and adhesives, they hit on the idea of using clear, flexible straps made from a durable, eco-friendly material. It was a bit like the clear straps on some bras but softer and more forgiving. They found a blend of nylon and spandex that felt smooth and breathable and paired it with the clear hip straps. The result was a seamless thong that practically disappeared under clothes.
They decided to call the brand “Stringys” because the thong’s thin, almost invisible straps reminded them of strings. At first, they made a few samples and handed them out to friends to test. The feedback was positive: the thongs were comfortable and actually did what they promised — no visible lines, no digging in, just a smooth fit. Encouraged, they produced a small batch and launched the brand online.
Their first big break came when a few fashion influencers featured Stringys in their styling videos. One post led to another, and soon orders were coming in faster than they had anticipated. The appeal was clear: Stringys offered the freedom of going commando without the risk. Olivia and Elvira handled packing and shipping themselves at first, often working late into the night from Olivia’s living room. As demand grew, they started looking for a small warehouse space to keep up.
The thong itself is designed for simplicity. The body is a seamless, raw-edged fabric made from a lightweight blend of nylon and spandex. The clear side straps are made from a latex-free, biodegradable material that clings gently to the skin without feeling sticky. Olivia and Elvira made sure to include a soft cotton panel for comfort. They wanted Stringys to feel good whether you were wearing jeans, leggings, or a tight dress.
They kept the color palette simple at first, offering neutral tones that would suit any outfit. Eventually, they added more options as customers started requesting colors like blush pink and deep navy. They also created multi-packs so customers could stock up without paying full price for each pair.
As Stringys grew, Olivia and Elvira stayed hands-on, managing social media and responding to customer feedback. They loved hearing from women who said they could finally wear their favorite dresses without worrying about underwear lines. By mid-2025, they had sold over 40,000 pairs, mostly through their own website. They also started selling through a few boutique stores and upscale fashion retailers, expanding their reach without losing the direct-to-consumer focus.
What started as a casual idea between friends turned into a real business. Olivia and Elvira still work together every day, coming up with new designs and thinking about how to keep improving the product. They’re focused on keeping it simple: one problem, one solution, one product done right. Stringys is more than just underwear to them — it’s about giving women confidence in their own skin without the distraction of uncomfortable or visible underwear.
For Olivia and Elvira, it’s not about creating a fashion empire. It’s about solving a simple problem with something that just works. They’re proud of what they’ve built, and they’re still experimenting with new ideas, but for now, they’re happy knowing that Stringys has made one small part of getting dressed a little bit easier.
