Not an endorsement of amazon, btw, just lazy
Take Ivy (Amazon link) https://www.amazon.com/Take-Ivy-Shosuke-Ishizu/dp/1576875504 Not sure if it's what you're asking about...specifically Ivy League fashion, possibly too late for what you're talking about. I love it though
Apparently it was featured in Take Ivy, which was published in 1965 in Japan as a fashion guide for "Ivy Style"
Take Ivy is classic.
if you say so just because of the t-shirt you might be mistaken. EDIT: You0re definitely right about the continent though: http://www.amazon.com/Take-Ivy-Shosuke-Ishizu/dp/1576875504
It looks incredibly similar to Cambridge, UK, nut it may well be Princeton.
