It's hard to believe it's been 20 years since Friends hit our TV screens. Partly because we'd rather not accept how old that makes us, but also, with old episodes being screened on a constant satellite TV loop from the show's demise until, presumably, eternity (check Comedy Central right now, Friends is almost certainly on), it's tricky to get a handle on its exact location within the space-time continuum.

But if you need proof that our first meeting with the Central Perk loiterers really did take place two decades ago, you only need to observe that the clothes they wore back in the mid-'90s have now completed a full turn on the great ferris wheel of fashion and become trendy again. Yes — as unlikely as it may have seemed until very recently — the comfortable, vanilla, almost anti-style basics of Ross, Rachel, Chandler, Phoebe, Joey and Monica are very much the bees knees again. Don't believe us? Check out five key style moments from the 10 seasons, and the lessons they teach us today.
