Everyday underwear is the unsung hero of consumer wardrobes. It is a huge, global garment category, but one of the most challenging in which to differentiate products and ensure purchase satisfaction.

Although style is important, consumer judgements are primarily based on practical criteria. The key is durability. Frequent wear and wash cycles can cause rapid deterioration in garment comfort and fit as well as progressive discoloration. Garments made from fabrics with LYCRA® fiber maintain their original shape and superior fit longer than those with ordinary spandex (elastane). Innovations in color technology offer long-lasting brighter whites, more intense blacks and richer colors in between.

Mills can learn more about how to create consumer value and compete more effectively in this category through the LYCRA® fiber fabric certification program for cotton underwear.
