What Is a G-String, the Underwear Style With Barely Anything in the Back? A Lingerie Founder Explains
We don’t blame you if the term “G-string” throws you for a loop. Depending on how familiar you are with underwear terminology, it may sound like just another name for a thong. But here’s the thing: G-strings are their own cut—and they offer about as little coverage as underwear can.
In fact, when it comes to showing as little fabric as possible, few underwear silhouettes come close.
“A G-string is one of the most minimal underwear silhouettes,” Melissa Wedge, founder and creative director of Australian lingerie and sleepwear brand Nude Theōry, tells Undies. Basically, the defining feature is the very narrow strip of fabric at the back, which gives you far less coverage than briefs, cheekies, or most thongs.
For those of you wondering, Wait, what exactly counts as a G-string? there can be a little variation from brand to brand. While it isn’t always labeled consistently, a G-string generally has a small front panel with a thin strip or string running between the cheeks, plus very little fabric around the hips. (So yes, the name is pretty literal.) Ahead, we’re breaking down what a G-string is, how it differs from a thong, and what to know before wearing one.

What Makes Underwear a G-String?
A G-string is defined less by what it has than by what it leaves out. The front generally offers fuller coverage, while the back is reduced to “a very narrow piece of fabric or string,” the founder explains. Around the hips, there’s typically very little fabric as well, so most of the coverage is concentrated at the front.
That barely-there construction also explains where G-strings tend to come in handy. She calls being discreet under clothes “one of the biggest benefits,” particularly under clothes that sit close to the body or are made from thinner fabrics where visible underwear lines are the last thing you want showing through. And while designs vary a little from brand to brand, the narrow back is the feature that sets the G-string apart (so don’t judge the pair by the front alone).
How a G-String Should Fit
Because there’s so little fabric, every part of the fit matters. “Fit is everything, particularly with such a minimal silhouette,” she says. A G-string should sit securely against your body without digging into your skin, while the waistband should stay in place rather than rolling or slipping as you move.
The back matters just as much. The designer says it should sit “naturally and comfortably without requiring constant adjustment,” so if you’re already fixing it after a few minutes, the fit probably isn’t right. And then there’s the fabric. Because there’s so little of it, she recommends looking for something soft and breathable rather than anything that feels restrictive or irritating against the skin.
How G-Strings Differ From Thongs
The biggest difference between a G-string and a thong is how much fabric you get at the back. Both are meant to give you very little coverage, but a G-string takes that idea further, usually replacing the wider back of a thong with a much narrower strip or string (more on G-strings vs. thongs here!).
That can make a relatively big difference under clothes, in our opinion. “Because a G-string has even less fabric at the back, it can be particularly effective at minimizing visible panty lines,” she says. That being said, she points out that the cut isn’t doing all the work. Fabric, seams, and construction matter as well, and “a well-designed thong can also be virtually invisible under clothing.” So if avoiding underwear lines is your main concern, you don’t necessarily have to choose the pair with the least fabric.
