Fashion and trends follow a few predictable patterns. Whatever was big 20 years ago always seems to come back, albeit just a bit twisted and different. There was a small 80s revival in the last decade, so we can reasonably expect a 90s revival this decade. What makes that even more appealing is that the same cycle is going to be reinforced by social and economic trends that should produce a serious Grunge revival any day now.
Probably the last thing anyone wants to hear is fashion advice from someone as unhip / uncool as I am. As unplugged-in as I am it’s impossible to catch a few things even before they become very popular, however, and I think this one will catch on. It’s a question of where it comes from and how it plays out.
