My uncle used to get their catalog. At that time it was mostly fairly "manly" looking sportswear, really not bad looking in the catalog. Of course, that was in the waning days of the "lumberjill" look among the gay set back in the '70s. My uncle and I visited their store in West Hollywood once, but we found the apparel, while not bad stylistically, to be very shoddily made.
The current catalogs are incomparably more louche and over the top. (I am only familiar with the contents of the current catalogs from what I have seen posted on these fora.)
As I have remarked elsewhere (here or on AAAC, I am not sure which), the International Male catalog certainly puts paid to the notion of gay men as arbiters of taste, elegance and style! I wonder what Carson Kressy thinks of it all. (Actually, about 85 or 90% of what he counsels in his book, most of us would agree with, believe it or not.)
