Zendaya is the opposite of a "smug married", except on last night's red carpet for Spider-Man: Brand New Day, which took place in a meltingly-hot Paris, she had every right to be; not so much because of her husband but because of what she had chosen to wear: a gorgeously oversized T-shirt. Vintage, and naturally depicting the film's titular superhero, it was cool in both senses of the word; a lesson in undone summer dressing and not trying too hard.
