Top 7 Customer Complaints about Underwear Products and Priority Improvement Guidelines for Seamless Lingerie Manufacturers

End User Complaint: Many ladies report that seamless underwear often varies significantly in size across different brands and styles, which can lead to dissatisfaction and a high volume of returns. Consumers frequently recommend "sizing up" or advising others to check specific measurements.

S·KAIFEI Promise: Our seamless underwear factory offers custom-fit seamless panties tailored to customers' body or curvy needs. We provide detailed size charts in both centimeters (cm) and inches, including key measurements: waist circumference, hip circumference, front rise, back rise, gusset width, and waistband width. Additionally, we have extensive experience in manufacturing plus-size seamless panties, ensuring optimal fit and comfort for curvy figures.

End User Complaint: Ladies often express discomfort with seamless underwear due to small gussets, thin materials, or irritating seams. Online discussions frequently highlight preferences for a wider gusset in seamless designs, emphasizing comfort as a critical factor.

S·KAIFEI Promise: Our underwear manufacturing company can enlarge the size of the 100% cotton gusset as per customer requirements. We consistently use soft, breathable 100% cotton for the underwear’ crotch, ensuring worry-free wear even for those with sensitive skin. For customers needing a thicker cotton material, we offer options with increased thickness plus breathable holes to maintain optimal ventilation in the gusset area. Throughout the design and production process, we ensure our seamless panties meet the diverse needs and preferences of all types of customers.

User Complaint: Customers complain about loose waistbands that lose elasticity after washing, leading to rolling up at the thighs or waist.

S·KAIFEI Promise: Our underwear ODM factory conducts rigorous tests on all panties, including elastic rebound testing for the waistband and elastic retention assessment after 50 wash cycles before the shipment. This ensures the panties maintain their elasticity even after repeated washing, keeping the waistband and leg openings snugly fitted to the body’s curves at all times.

User Complaint: Synthetic materials like polyester or nylon receive complaints for poor breathability and irritation during exercise, especially among sensitive skin users who prefer cotton.

S·KAIFEI Promise:SKAIFEI Promise:Our seamless underwear OEM China offers customized "golden ratio" blending of polyester and nylon based on customer requirements, as both materials have their unique strengths and characteristics:

Polyester: Advantages include wash resistance, wrinkle resistance, moderate cost, and quick-drying properties, with slightly inferior elastic recovery.

Nylon: Boasts high elasticity, softness, smoothness, wear resistance, and excellent body fit, but has average moisture absorption.

The core of blending these two materials is to leverage nylon for enhanced elasticity and touch, while utilizing polyester to ensure durability and stability. We further incorporate 5%-20% spandex (an indispensable core component for elasticity) to achieve superior stretch performance.

For our seamless panties for women, the standard golden ratio is typically 70%-80% nylon + 10%-20% polyester + 8%-12% spandex. This optimal formulation ensures a body-hugging fit, no rolling edges, and no indentations. Additionally, the panties maintain their shape even after repeated washes.

Our seamless panties for lady are clearly labeled on the panties using heat transfer technology, allowing customers to select the most suitable option for themselves. Furthermore, the gusset is made of 100% cotton, providing exceptional comfort for those with sensitive skin.

User Complaint: Users mention products losing shape, stretching, or fading after just a few washes, especially from higher-priced brands.
