Ubras is a Chinese intimate-apparel brand founded in 2016 that develops comfortable, adaptive underwear and clothing for women across different body types and stages of life. The company pioneered the sizeless-innerwear category in China, using high-elasticity fabrics, bonded seamless construction, and wireless designs to create bras and underwear that accommodate a range of body shapes with simplified sizing. Its current portfolio spans bras, underwear, shapewear, loungewear, sleepwear, and other close-to-body apparel.

Ubras has expanded its approach to comfort into specialized products for different ages and use cases, including active lifestyles, teenagers, and post-surgery care, while continuing to invest in materials, construction techniques, and fit. The brand has served more than 50 million customers worldwide and has expanded from its online base into physical retail and international markets including North America, Southeast Asia, and Europe. Ubras has also helped formalize the sizeless category through technical standards, including participation in China’s first dedicated industry standard for free-size knitted bras, which took effect in 2026.
