Everyone needs to know how clothes should fit, and it often takes some trying on. There's no shame in slipping on a pair of jeans or blazer to see how it fits. Keep everything in perspective, it's a retail store, not your personal runway show. Clothes are in the store so you can try them on, and decide whether you want to make a purchase or not. When you grab 17 items and lock yourself in the fitting room for an hour, you're not only a jerkoff, but potentially also stopping other customers—with intentions to make a purchase—from the opportunity of accessing an open fitting room. Unless you've worked retail before, and feel sympathy for the employee, there's a good chance the fitting room is an absolute fucking disaster when you waltz out to upload your style shots on Instagram.
