Thanks, John. I considered the website question for a while and ended up deciding to just exclude any other websites or forums. Tutee's stuff on LL is great, blacktieguide.com is great, but then do we include asuitablewardrobe and putthison too? Link to SF threads that are particularly informative? Maybe it's just a copout not to have to go through much stuff and make editorial decisions, but I think there's so much out there online, and a lot of it is well-linked on this forum generally, that I just wanted to narrow the focus of this thread to information that's done in a book format.
The Molloy book looks very specifically business-oriented, almost like a career counseling book rather than a style book. Is that true? I remember I looked at it before and didn't put it on the list for some reason, maybe that was it. It could be I was just tired of putting in links. What's your experience with this book, John?
You may be right about the concept being more manageable if limited to the printed page. As AeroCarl has pointed out, BTG may appear in book form sometime in the future, so there is (possible) reason for hope from its devotees for its inclusion here.
I read Dress for Success, in the words of a professor of mine, "in a different dispensation," i.e., years ago, in college. As I remember, it advised which color and pattern combinations in suits, shirts, and ties were most appropriate to achieve specific effects. IIRC, it was mainly high-end business related. However, it may be an interesting study whether any advice in it is still considered relevant for the same professions today.
