内衣 (nèi yī): underwear

Before running, she changed into a sports bra, so she would be more comfortable during exercise.

When traveling, I put my undergarments and socks separately in small bags in my suitcase.

The undergarments in this store are all pure cotton and very comfortable to wear, so many customers like to shop here.

Mom reminded me that undergarments should be changed and washed daily for good hygiene.

She bought a lace undergarment set online and planned to wear it on her wedding anniversary.
