This shirt features a traditional Japanese 4-character phrase (called a "yoji-jukugo" in Japanese).
These phrases condense longer expressions and complex ideas into a concise form of four kanji characters.
This design provides the kanji characters, read top to bottom, how to say them, and a short expression of the meaning in English.
In this case, the sound of the third character is a long "o" sound, which is indicated by the "u" at the end. Say it to rhyme with "row", not with "you".
How about two of these for a couple?
This t-shirt has a classic fit (not form-fitting), with a thick cotton fabric.
• 100% cotton (Heather colors contain polyester)
