7. The Scandalous Victorian Bikini
You see this toe-to-neck swimsuit? This was seen as about as shocking as running into the waves topless and with a thong on. Annette Kellerman didn't want to be weighed down by wool skirts and frilly lace as she did laps in the ocean and so she put on this sensible suit - only to be arrested for indecency!
