#NationalUnderwearDay: This video explains how men's swimwear has changed over the last 100 years

Apparently it is National Underwear Day today and what could be a better way to celebrate the day then to take a look at the evolution of men's swimwear in the past 100 years. While we all have a fair idea of how the women's swimwear evolved over the years, little do we know about the skivvies men have been wearing on the beach. Well certainly they are not just boardshorts, trunks or speedos. The swimwear men used to don during the period of 1915 to 1935 would look a little too funny if someone stepped out wearing them today. Check out this video and see if your choice of swimwear is old fashioned or avante garde.
