You've heard of the Kate Middleton effect, but have you heard of the Molly-Mae effect? The former Love Island star has an incredible amount of influence on UK shopping habits and fashion trends, and she often causes jackets and outerwear to sell out as soon as she posts herself wearing an item on Instagram. The problem, however, is if you're even slightly late to a Molly-Mae-set trend, you won't be able to get your hands on the buy. Case in point: Zara's Bomber Jacket, usually £79 but currently sold out.
