I have no idea. I am too young to have "been there", so I must rely on older members and writers. My post above was to spark some thinking and ask a few questions about the word "trad" and our use (or possible mis-use) of the term.FerrisBueller said:I like your assumption that the Ivy shops may have focused more on sportswear (which may have ultimately morphed into "preppy")? Were the suits cut differently? You had suggested that perhaps cuffs were not originally on ivy style suit pants. That would make sense to me.
Perhaps Brooks Bros. was traditional, and university shops were ivy??? Am I on the right track?
Today I started reading Paul Keers' book, A Gentleman's Wardrobe, which is about classic British clothing, but he makes a few statements which (obliquely) suggest that pre-war "Ivy" was rather different than post-war "Ivy". I am beginning to think the differences may have been quite pronounced, a view which is supported in part by a passage in a French-published but English-language book (which I saw in a bookstore in Montreal) which defined "Ivy League" style as something quite different than Boyer's article, and dated it to the pre-war period.
(Ironically, Keers' book has a double-page photo of a BB OCBD and it looks really, really nice, with much longer collar points, and possibly softer fabric than today. The book dates from 1988.)
