無精ひげ

There is another way to describe stubble:

• 5 o'clock shadow

This expression describes stubble that appears on a man's face late afternoon despite shaving in the morning.

5 o'clock shadow is a noun-phrase.

Example:

• Your 5 o'clock shadow is terrible. You should buy a new razor.
• My facial hair grows very quickly so I always get a 5 o'clock shadow.

Back in the 1980s, designer stubble was fashionable. The pop singer George Michael was famous for his designer stubble.
