I like the full skirts - which followed on from the "New Look" which Dior launched in 1947, so not truly a 50s fashion as the original article says. I'm not so keen on the straight pencil skirts which were also around then, but more towards the late 50s.
The shoes are interesting, none of them would really look out of place today, and the only styles which are missing are the thin stiletto heels and very pointed winklepicker toes.
Essentially there is only so much that fashion can do, and short of crinolines, bustles or fathingales coming back into fashion (very impractical but possibly OK for evening wear) it has to be a re-hash of previous styles and sometimes mixing bits from different eras.
