Ubras is a Chinese intimate apparel brand founded in 2016, focused on making underwear more comfortable, simpler, and adaptable to different body types. The company pioneered sizeless innerwear in China, using highly elastic fabrics, bonded seamless construction, and wire-free designs to create bras and underwear that provide a flexible fit and all-day comfort without relying on conventional sizing systems.

Building on its core sizeless products, Ubras has expanded across bras, underwear, loungewear, sleepwear, and other everyday essentials, as well as specialized offerings for teenagers, active lifestyles, and post-surgery care. The brand has served more than 50 million customers worldwide and continues to extend its presence through physical retail and international markets.
