Just a silly question I was thinking of. I'm guessing they're very similar, with the Trads focused on formal clothing from the 50s / 60s, with the prep look based on pastel colored casual clothing.
Thanks - my understanding was that 'preppy' was very much an invention of the 70s / 80s (and hence, distinct from the Ivy look described here.) Perhaps I'm mistaken.
Interesting - thank you.
It might be that one begins as "Preppy", morphs into "Ivy", then graduates and goes to work and morphs again, into "Trad", and then retires, and in one final morph, goes back to "Preppy" (but even 'Preppier") than at the beginning.
At least, that's the way it's been with me, although most of my morphing took place before the words "Preppy", "Ivy", and "Trad" were invented. We all just looked that way, but we didn't know that some day people would invent words for the way we all looked.
