A string thong that rides up is usually a fit or fabric issue. Learn how to diagnose the cause, adjust your size, and choose styles that stay put all day.
Quick answer

Try going up one size for a looser fit, or choose a thong with a wider, softer waistband and cotton-lined gusset for better grip and comfort.
Symptom: The center seam or sides creep up
You put on your string thong in the morning, and by midday the fabric has migrated into places it shouldn't be. The sides curl, the back rides up above your waistband, or the gusset shifts out of place. This isn't just annoying — it can cause chafing and make you constantly adjust throughout the day.
Likely cause: Wrong size or fabric stretch
The most common culprit is a thong that's too small. When the elastic is under constant tension, it pulls the fabric upward. A too-large thong can also ride up because there's not enough tension to keep it flat. Fabric matters too: slick polyamide blends without enough elastane can slide against skin, while a cotton-lined gusset helps anchor the garment.
Corrective action: Check your size and choose the right materials
Measure your hips and waist and compare them to the brand's size chart. If you're between sizes, try the larger one for a thong — you want a gentle hold, not a tight squeeze. Look for styles with a soft, elastic-free waistband that lays flat, like the Comfie Thong 3 Pack from Never Say Never, which uses wide scalloped lace that stays put without digging in. The Fiorita String Thong offers a mid-rise fit with a cotton-lined interior, which reduces sliding. For a budget-friendly option, the Carmela Thong has minimal rear coverage and a cotton gusset, but its narrower lace may ride up more on some body types.
When to stop and choose another option
If you've tried sizing up and switching to a style with a wider waistband but the thong still rides up, your body shape may not be suited to a string thong. Consider a mid-rise bikini or hipster cut instead. These provide more coverage and a different seam placement that stays put on curvier hips or straight figures alike.
Diagnosis: Why your string thong rides up
- Symptom: The thong fabric creeps upward, sides curl, or the gusset shifts out of place during wear. This is a fit or fabric issue, not a design flaw.
- Likely cause: Thong is too small (overstretched elastic pulls up) or too large (loose fabric slides). Slick polyamide blends without enough elastane also contribute. Size up or choose a style with more cotton and a wider waistband.
- Corrective action: Measure hips and waist, compare to brand size chart, and try the larger size if between sizes. Select a thong with a soft, elastic-free waistband and cotton-lined gusset. The Comfie Thong 3 Pack or Fiorita String Thong are good starting points.
- Stop point: If after sizing up and switching to a wider waistband the thong still rides up, your body shape may not suit a string thong. Switch to a mid-rise bikini or hipster cut for a stay-put fit.
Product details that matter
- Comfie Thong 3 Pack: Mid-rise lace Comfie thong 3 pack in tonal shades. Soft stretch, scalloped Never Say Never lace that lays flat. Wide, soft lace, elastic-free waistband. The elastic-free, wide lace waistband reduces the chance of the thong rolling or riding up, making it a good first fix to try.
- String Thong: Mid-rise string thong. Soft elastic band at sides. Low-rise fit with minimal back coverage. Cotton-lined interior for everyday comfort. The cotton lining adds grip against skin, and the mid-rise fit sits lower on the hips, which can reduce upward migration for some body types.
- Thong: Classic thong style. Minimal rear coverage. Cotton lined gusset. Lace: 86% polyamide, 14% elastane. The higher elastane content gives this thong more stretch and recovery, but the narrow lace may not stay as flat as a wider waistband style.
