SEAMLESS
Custom Women's Seamless Thong | OEM Underwear Manufacturer
Custom seamless thong underwear manufacturer offering OEM/ODM production, private label customization and bulk manufacturing solutions for lingerie brands.
Product Overview
This custom seamless thong is knitted in one piece on seamless circular knitting machines — a smooth, comfortable fit with minimal seam appearance, developed for lingerie brands, private label brands and everyday underwear collections. Construction, fabric and branding are adapted to your requirements through our OEM/ODM development.
SML INTIMATE supports private label underwear development from yarn selection to bulk production: the thong is produced entirely under your brand, with custom manufacturing support at every step from first sample to shipment.
Customization Options
- Yarn/material selection: nylon/spandex blends and cotton-rich options
- Color customization: developed at the yarn stage and approved on the actual knit
- Waistband branding: logo knitted into the waistband
- Labels: woven, printed or heat-transfer
- Packaging: polybags, hangtags and export packing to your specification
- Size specifications: grading across your full size range
Manufacturing Support
SML INTIMATE supports the full OEM/ODM development chain: design confirmation against your tech pack or reference sample, sample development in your selected materials and colors, fitting adjustment until approval, and bulk production with QC photos before shipment.
Each stage is confirmed with you before moving to the next, so the finished thong matches your specification — knit structure, fit and branding are approved on physical samples before bulk runs.
