馬子にも衣装 [まごにもいしょう] – “clothes make the man”
馬子 [まご] – packhorse driver
- 馬 [バ・うま] – horse
- 子 [シ・ス・こ] – child
衣装 [いしょう] – clothing; costume
- 衣 [イ] – clothing
- 装 [ソウ・ショウ・よそおう] – attire; disguise
I’m guessing that the idea of this one is “you can even dress up a packhorse driver and make him look nice.” Not sure what they had against packhorse drivers.
