In the world of women's wear, trends are the name of the game. Alexander Wang makes military jackets with leather sleeves? So does Zara and H&M. Isabel Marant makes sneakers with heels? Watch out for interpretations from Nike and adidas. Women will cop a similar version of a piece, but diehard menswear fanatics know there's nothing like the real thing. Just like a sneakerhead won't ever step foot into a pair of fakes or a colorway that isn't exactly right, so too goes the menswear nerd. Why else do you think a Jil Sander whale sweater would be so high in demand? Hype springs eternal.
