• Structure: 夏服 (なつふく) combines summer 夏 and clothing 服 to denote clothes intended for the warm season.
• Basic usage: It covers seasonal uniforms and lightweight garments taken out when summer approaches.

2. Common pitfalls and similar expressions

  • 夏服 classifies clothing made or designated for summer rather than any garment worn incidentally on a warm day.
