We have good news for anyone who doesn’t want visible panty lines. Seamless underwear comes in many shapes and forms, including briefs and thongs. So how should you decide which is best for you? Keep reading for our tips. We got you (and your backside) covered.

What Is Seamless Underwear? 

First, let’s review the basics. Seamless underwear has no visible stitching, and thus no visible panty lines. At Uwila Warrior, we achieve this with laser cut edges, as opposed to traditional elastic or sewn edge leg openings. 

The best seamless underwear is made with super lightweight and stretchy fabrics that mold to your body and help prevent wedgies. “The fabric lays super flat on your body, making it undetectable under clothing,” explains Samantha Benassai, Uwila’s Product Development Manager.

Seamless Briefs vs. Thongs 

At Uwila Warrior, we believe in wearing what makes you most comfortable, so you can focus on more important tasks during your day. Great underwear is underwear you look and feel good in. “Some women enjoy wearing thongs, but for those who don't, our hipster cut Happy Seams brief will ensure that you don't have panty lines, making it an ideal substitute to a thong,” Samantha notes. She adds that these briefs layer well under pants, leggings, skirts and dresses, in styles that both form fitting and more relaxed.

Uwila’s briefs are also cut to go around your natural body shape, unlike others that rely on elastic and expand which can cause dimples and panty lines where they pull in. Elastic can’t recover back into place as you move throughout your day. If underwear is expanding on your body and is pulling in, it's not going to slide back out to where it is supposed to be. And that’s when you end up with an uncomfortable wedgie. No, thank you. 

Now let’s discuss that thong-th-thong-thong-thong. While thongs might not be for everyone, they do create a super lightweight feeling that still gives the coverage you need. If you’re an active person, you’ll appreciate that thongs stay in place (especially a Uwila thong!). And less material can feel more comfortable in warm weather. 

At Uwila, we’ve created a thong that even skeptics will love. “We believe we have perfected our thong and made it the best possible experience for the wearer,” Samantha explains. Uwila’s VIP Thong has laser cut edges at the waistband and leg openings to ensure it's panty-line free. There are also and thermowelded side seams, to give a smooth appearance under clothing.

With our thong, we have also eliminated the back crotch seam, so there is nothing to dig in back there and cause discomfort. “We topped it off with a cotton lining at the crotch that is heat bonded on all four edges,” Samantha explains. This means it lays flat and doesn't rub or irritate, for added comfort in a sensitive area. 

Maybe the answer isn’t thong or brief, but both.
