If you’re sick of throwing shade to the fickle weather we’ve been having this summer, fear not. Model Sheila Marquez rocked up to the ICB autumn campaign launch in New York this week and played sartorial agony aunt to SAD sufferers everywhere by showing us how to get major mileage from a summer dress. The answer? A metallic sweater. The foil texture adds sass to an otherwise monochrome outfit and gives it a grown-up rather than a dress-down-Friday vibe. Slide into some slip-ons (choose flatforms for a bit of extra height) to keep it summer appropes and you’re good to go. No sun, no problem.
