We’ve talked beauty, we’ve talked fashion, and now we’re here with what lies beneath: your lingerie. In less than three minutes, this video takes us through a 100-year-long journey through styles of skivvies that women first thought would impress men (the early days), and now wear to impress themselves and feel good in their own skin (today). The journey carries on mostly the way you would expect, with just a couple surprises. For example, the styles of lingerie surprisingly do not get necessarily skimpier over time, but instead evolve to embrace comfort and femininity. Watch below to find out what era of underwear (underwera?) you belong in.
