ワイシャツ
ワイシャツ · waishatsu · JLPT N5 · noun
shirt
👔 ワイシャツ = white shirt, clipped: waito shatsu → wai-shatsu
Etymology: borrowed from English white shirt, with the middle squeezed out. Because ワイ sounds like the letter Y, it is often written Yシャツ. It now means any collared dress shirt, whatever the colour.
