'Scanties' used to be a term for wispy feminine underpinnings, in the inter-War era, as was 'skimpies'.
I remember in the song "Sign," from the musical "Annie," which is set around the mid-1930's, Oliver "Daddy" Warbucks sings to Miss Hannigan (the girls' orphanage director), while showing her a photograph taken by a private investigator, "Here you're dancing in your scanties, with some old geezer called Little Caesar."
That's my only clearcut recollection of that term, but "skimpies" is one I've never heard.
Of course, here in the U.S.A. there's a professional basketball team called the New York Knickerbockers, usually shortened to "Knicks," obviously referring to boys' knee-length trousers from about a century ago--or actually (I'm guessing) "Father Knickerbocker," supposedly symbolizing New York City, whom that style of pants presumably was named after.
I'd agree that certain sporting apparel isn't designed to be worn with regular underwear, male or female--it is interesting that cheerleaders and female tennis players wear panties/knickers designed to be viewed in public, and that's considered quite acceptable. (How critically different are cheerleader 'spankies' and tennis panties from regular feminine underwear, hmmmm?)
