Whether you prefer thongs, bikinis, or boyshorts, one thing we can all agree on is that pantie lines are the absolute worst. No matter how fire your outfit is, a visible pantie line can quickly ruin everything. Luckily, there are a variety of seamless panties on the market to keep all of your outfits looking smooth and flawless. For the best no-show fit, look for underwear with flat-stitched seams that are made from thin, stretchy materials. Fabrics like spandex are ideal because they naturally conform to the shape of the body.
