Way back in 2013, Lululemon faced some flak for selling yoga pants that were revealingly sheer. As people discussed the see-through pants, a question emerged: what should you be wearing under tight yoga pants, anyway? Standard underwear? Some kind of fancy yoga pants thong?

"Regular" underwear with yoga pants might be too constricting and cause VPL (that's visible panty lines, which some people would rather not display). Thongs take care of the lines but can lead to comfort issues. So do you just go commando?

Sites from Slate to The Frisky have all weighed in on what to wear under yoga pants, but a consensus has never been reached—it is a question of personal taste, after all. But I wondered if, given a large enough sample of practitioners of yoga, I could find a definitive answer to what to wear under yoga pants ... or at least which option was most popular. The results were pretty surprising.

People prefer regular underwear under yoga pants.

Specifically, a classic bikini cut.

(Ed. Note: we personally like seamless bikini yoga panties because they're comfy without showing any lines.)

Before I started, I would have bet that most people would say they just went commando under their yoga pants. To my surprise, it ended up as the least popular choice, and most yogis said they preferred to wear regular underwear, specifically, a classic bikini cut. About 45% of the people who said they wore underwear mentioned that the bikini cut was their preferred style.

So how did we get these results?

The Methodology, AKA, A Really Weird Survey

I created a survey using SurveyMonkey and made sure that anyone who answered it would remain completely anonymous. I advertised it to yogis I knew and posted it on Facebook, Twitter, and Reddit. The survey asked respondents how old they were, how long they've been practicing yoga, and what they typically wore under their yoga pants, with multiple-choice answers for all three questions.

The third question had three possible answers: nothing, a thong, or underwear (not a thong). If someone chose non-thong underwear, they were asked to specify what type of underwear they preferred (bikini, boy shorts, etc.) in a text box. I also included a text box at the end of the survey where participants could leave comments if they wanted.

Hundreds of People Respond

I had hoped to get about 100 responses so that I could make some deduction about how yogis prefer to dress their nethers. I ended up getting more than 400.
