You can wear anything you want nowadays. Anything. New, not new, forgotten, rediscovered. If it’s old, then it’s not old, it’s vintage, should anyone be so involved in useless time filling as to actually try to tell you your clothes look old.
Individuality and personal style are on the rise. Whatever makes you feel like yourself, you wear it. Regardless of whether you saw it in a magazine, have loved it forever or reverted to (adult versions) of things you wore as a child.
And finally, the fact that you can find clothes your favourite TV show characters wore ONLINE.
