Illustrative situation
A brand wants to add a thong and a G-string to its underwear line, and the factory sends samples that look right on the table but feel uncomfortable when worn.
Main answer
Men’s thongs and G-strings depend on a well-shaped pouch, a back strap of comfortable width and soft elastic, and they need careful size grading and wear-testing, because small errors in shape or elastic tension show up as discomfort. Treat them as a specialist style with its own pattern, not a cut-down brief.
Pouch and front shape
The pouch should give room without bagging and hold its shape. Use a fabric with enough stretch and recovery, and test how the seam sits against skin. Compare pouch depth across sizes, since a pattern graded evenly may not fit well in the smallest and largest sizes.
Back and waistband
A thong has a narrow back panel, while a G-string has a thinner strap. The width, the elastic softness and the finish of the edges decide comfort. Check that the elastic does not roll or dig in, and that stitching is flat. See the briefs manufacturer page for related styles.
Fabric and finishing
Seamless or bonded edges can reduce marks under clothing. Choose soft stretch knits with good recovery, and check dye fastness, since these garments are worn close to skin. Keep trims small and flat.
Testing and feedback
Run a small wear test with a handful of volunteers across size groups, and collect notes on pouch comfort, strap width and elastic feel after a full day. Adjust the pattern before bulk, and record changes so the factory follows the final version.
Hygiene and labels
Because these are intimate garments, many retailers do not resell opened packs, so seal each pair and check the hygiene liner or gusset construction. Make sure the fibre content and size are printed where the customer can read them without scratchy tags.
Packaging and sales
Underwear is often sold sealed, and many retailers do not accept opened returns, so use sealed packs and say so on the product page. Offer a clear size chart and photos that show the cut on a model or a form.
Fact, recommendation, uncertainty
- Established fact
- Comfort in thongs and G-strings depends on pouch shape, strap width, elastic softness and size grading, and each size needs separate checking.
- Recommendation
- Develop a dedicated pattern, wear-test several sizes and use soft elastic and flat finishing.
- Uncertainty
- Fit preferences are personal and no single design suits all wearers.

No single official source defines this, so this answer is a recommendation based on how production and buying are commonly organised. Confirm every figure and term in your own quotation.
More perspectives from the team
Three further views on the same question, each by function. They add conditions and limits to the main answer; they are editorial notes, not customer reviews.
Sino Finetex Editorial Team Sourcing
Ask the factory to make fit samples in at least three sizes and to share the elastic specification. Limit: elastic suppliers may change between sample and bulk, so confirm in writing.
Sino Finetex Editorial Team Product selection
Start with one thong style in a basic colour and add others after feedback. Limit: a narrow range may not meet all customers’ preferences. Give each style a clear name and an honest size and cut description.
Sino Finetex Editorial Team Quality & care
Check seams and elastic for comfort after washing and inspect stitch quality at the pouch. Limit: tests on a table do not replace wear-testing, so ask real wearers for feedback.
