Why Do Thongs Feel Uncomfortable, and How Do I Fix It?

Thongs usually feel uncomfortable for one of three reasons: the size is wrong, the fabric doesn't have enough stretch or grip, or the cut just doesn't suit your body or the way you move. The fix is almost always about fit and fabric rather than toughing it out — sizing up slightly, picking a softer stretch material, and choosing a wider gusset over a thin strip solves most of it.

Why Thongs Ride Up in the First Place

Riding up happens because there's very little fabric at the back to begin with, so any movement — walking, sitting, bending — has more room to shift it. A thong that's too tight digs in and gets pulled further up with every step. One that's too loose has nothing to hold it in place, so it slides. Either way, the underlying issue is usually fit, not the style itself.

Fabric plays a big role too. Slippery materials like satin or silk look lovely but have less grip against skin, so they're more prone to sliding around. A stretch cotton or modal blend tends to stay put far better, simply because it has more friction and flexibility to move with your body instead of against it.

Common Causes of Thong Discomfort

• Wrong size. This is the most common cause by far — either too tight, which cuts in and rides up, or too loose, which bunches and slides.

• Rigid or slippery fabric. Fabrics with no stretch or too little grip struggle to stay in place through normal movement.

• A worn-out waistband. Elastic loses its stretch over time, so an old favourite that used to fit well can start riding up even if your size hasn't changed. Regular washing habits play a part here too — our guide on whether lingerie can go in the washing machine covers how to wash delicate pieces so the elastic lasts longer.

• The wrong style for the activity. A delicate lace thong built for looks isn't built for a gym session, and a sports-specific pair isn't the most comfortable choice under a formal dress.

• Visible seams or a narrow gusset. Thin panels with hard seams have less surface area to distribute pressure evenly, so they're more likely to dig in.

Fixing Thong Discomfort, Step by Step

1. Check the size chart properly. Don't assume your usual size carries across brands or styles — measure yourself against the specific product's chart rather than guessing.

2. Choose a fabric with actual stretch. Look for cotton or modal blends with a bit of elastane rather than pure satin or silk if comfort matters more than the finish.

3. Match the style to the day. Save delicate lace for occasions and pick a soft, stretch style for anything active or long-wearing.

4. Check the gusset. A wider, breathable gusset panel is generally more comfortable than a thin strip, regardless of brand.

5. Retire worn-out pairs. If the elastic has gone soft or stretched out permanently, that's a sign to replace it rather than persist with it.

What Doctors Say About Fabric and Comfort

Board-certified OB-GYN Dr. Alyse Kelly-Jones has explained that cotton is one of the gentlest, most breathable fabrics for this part of the body, since it absorbs moisture rather than trapping it the way synthetic materials like nylon or spandex can. That's a big part of why cotton or cotton-blend gussets are so common even in lace or mesh thongs — it's the panel actually touching your skin.

It's worth keeping this in perspective, though. OB-GYN Dr. Jen Gunter has pointed out that more recent, higher-quality research hasn't found a strong link between underwear fabric and infections specifically, so breathable fabric is really more about day-to-day comfort than a strict medical rule. In other words, choosing cotton or a breathable blend is a sensible comfort default, not something to stress over if you occasionally wear something else.

Common Mistakes When Choosing a Thong

Sizing down for a smoother look. This almost always backfires — a too-small thong digs in and rides up more, not less.

Ignoring the gusset fabric. The overall lace or mesh design gets most of the attention, but the small panel against your skin matters more for comfort.

Wearing the same pair for everything. A thong that's perfect for date night isn't necessarily the right choice for a full day at work or a workout, and expecting one style to do everything usually ends in discomfort.

Quick Answers

Is it normal for thongs to ride up sometimes?

A small amount is normal with any minimal-coverage style, but constant riding up usually means the size or fabric isn't right for you.

Should I size up when buying a thong?

Often, yes — a thong that's slightly roomier tends to stay in place better than one that's tight, since a snug fit gets pulled further up with movement.

What fabric is most comfortable for everyday wear?

Cotton or a cotton-elastane blend is generally the most comfortable option for all-day wear, since it stretches with movement and stays breathable.

Are cheeky briefs more comfortable than thongs?

For some people, yes — a cheeky cut offers more coverage while still avoiding visible lines, so it can be a good middle ground if thongs consistently feel wrong. Our types of lingerie guide covers how cheeky, bikini and thong coverage levels compare.

Getting the Size Right

Since size is the single biggest factor in thong comfort, it's worth getting it right at the source rather than guessing. Sizing charts also vary more between brands than most people expect, so it's worth remeasuring yourself occasionally rather than assuming your size stays the same everywhere. Our bra and lingerie size chart guide walks through how to measure yourself properly.

Once fit and fabric are sorted, most of what people call an uncomfortable thong turns out to just be the wrong pair for their body — not a flaw in the style itself. A bit of trial and error with size and material usually gets you there faster than switching styles altogether.

Most thong discomfort comes down to a handful of fixable things — size, fabric and matching the style to the day. Get those right and the uncomfortable thong problem usually disappears.
