A trend that began in New York and didn’t let up. The best were oversized and loud at Marques’Almeida, one-shouldered and sexy at Victoria Beckham, naïve and eccentrically cut at Jacquemus. Monse, Tome and Alexander Wang also added spins on the trend, chopping them up and adding extra sleeves and collars and cuffs. Conclusion: if you don’t have a blue striped shirt in your wardrobe now, buy one, and do the buttons up wrong. Or wait until spring to buy the best.
