Plus Size Seamless Underwear
OEM Wholesale Manufacturer

Supportive, high-stretch seamless solutions for the curvy market. Sizing up to 4XL (RU 54+). Specialized in comfort for the Russian and European markets.

Engineered for Curvy Comfort

Standard seamless underwear often lacks the support and vertical stretch required for plus-size figures. At Hongcheng, we've developed specialized knitting programs specifically for the 2XL-4XL range.

  • High-Elasticity Yarn: Increased Spandex (Elastane) ratio for 360-degree stretch.
  • Reinforced Waistbands: Prevents rolling and provides gentle tummy control.
  • Extended Crotch Design: Better coverage and anti-chafing properties.
  • Anti-Bacterial Gussets: Graphene or Bamboo Charcoal options for all-day freshness.

Our "Invisible Lab" series focuses on the RU48-RU54 market, ensuring that plus-size garments maintain their shape after repeated washes.
