• Structure: 肌着, read はだぎ, means undergarments worn close to the skin.
• Basic usage: Use it for spare undergarments or a thick inner layer worn under other clothes.

2. Common pitfalls and similar expressions

• Compared with an outer layer

• Counting garments
  • The example's 肌着を二枚 refers to two undergarments. Do not add the idea of two complete sets.
