As with any clothing item, bathing suits have drastically evolved over the years. From the wool bathing suits of the 1920s (a sweating-slash-swimming hazard, we'd imagine) to the Pamela Anderson Baywatch cuts of the '90s, the bathing suit has been through quite the transformation.
It's hard to imagine now that the bikini, a swimsuit market staple, did not debut until 1946 (its apparent original home was the French Riviera). It was still common to cover up the belly button when the two-piece first hit the masses, so Taylor Swift -- a frequent belly button cover-upper -- would have been totally on trend.
Watch the video above to see how times have changed, and remember, no matter what you wear, you're always "bikini ready."
