Over the past 100 years men's swimsuits have got skimpier and skimpier, as you can see in this three minute long style evolution video.
The amazing folks at Mode.com are back, with a look at how men's swimwear has changed over the last century.
Sadly (or not, depending on how you look at it) there's no sign of the Borat mankini or the crochet man-thong of doom.
In the 1910s, swimwear was designed to make men look big and bulky...
Then regulations introduced in the 1920s dictated that men had to wear a skirt over their trunks to hide their modesty...
Abs were finally allowed on display after the ruling in 1937 that men could go topless...
And let's not forget the invention of the speedo in the 70s...
Watch the video above to see the looks in all their glory.
