These shirts that were designed to have the silhouette of 5 famous typefaces; Helvetica, Caslon, Baskerville, Courier, and Cooper Black.
In the world of typography, terms such as typeface, character, body, etc are used to describe the form of a letter. The reason why they use expressions closely related to a human body, is perhaps because each different letter has a distinct quality and personality, in a similar way that us humans are all unique.
The author at masa-ka.com says the following about these shirts:
In the designing process of these shirts, I aimed to capture the character of each typeface and tried to give them a unique look and presence once worn. By collaborating with Itaru Yonenaga, I feel we were able to produce a collection of shirts that is not only conceptual, but wearable as real clothes. I hope you will find your favorite shirt/typeface.
