Eight years before Marilyn Monroe's iconic scene in The Seven Year Itch, Katy Keene found herself fighting the gale for close on six pages. The strip's creator, Bill Woggon, frequently "spiced up" the action with pin up pages and mild innuendo from time to time (well, practically every issue TBH).
"Fanservice" elements were less common in other titles, though they managed to sneak in under the radar from time to time. Billed as "America's Typical Teenaged Girl," Ginger Snapp was a female version of Archie Andrews, complete with bright red hair and oddball supporting cast - although the similarities seem to have ended there. Unlike her better-known counterpart, Ginger occasionally treated her readers to gratuitous lingerie shots, complete with lacy black underwear and thigh-length suspender stockings.
Last (and possibly least) we have Owen Fizgerald's Moronica. Published by AGC
in the early 50s, Moronica (yes, that was apparently her real name) was
portrayed as ditzy, naive and accident-prone, ie a stereotypical "Dumb
Dora" played exclusively for laughs. Appearing mainly in the back pages
of Dizzy Dames (a more subtle title cannot be conceived), the
strip ran for less than a year before its cancellation in June 1953.
Strangely enough, the idea of an airhead blonde losing her clothes at
the drop of a hat didn't catch on too well at the time. Guess there's
just no accounting for taste.
