Finding the perfect underwear is no easy task, but that’s especially true when you’re on a mission to find the best pair to wear with leggings. To ease the struggle, we tapped

an expert in the field. Sarita Liu, the director of design and development for MeUndies, was kind enough to answer a few of our questions and provide some insider tips to help us determine what is most important when shopping for no-show undies.

In terms of specific design techniques, she says, consider the seams and edges. “Our No Show line features clean-cut edges and bonded seams, which means no stitching anywhere. We have designed our underwear to provide that barely there, all-day comfort,” says Liu. Fabric is also important. She uses a MicroModal spandex that will stretch and conform to fit your body perfectly (i.e., no unwanted lines).

And for our most burning question of all: Does it always need to be a thong, or can other styles work under leggings? “Our No Show Thong is very popular, but the No Show Hipster is also a good option for those who prefer more coverage. They are the ideal outfit game-changer and perfect to wear with anything skintight, semi-sheer, or thin,” says Liu.

There you have it. Keep scrolling to see the styles Liu has suggested, along with a few other recommendations.
