Like the runway shows themselves, Fashion Week traumas come in all shapes and sizes. There are the big woopsie-doodles like falling on the runway and the more subtle faux-pas like wearing sunglasses inside (no, it's not okay — not even as a headband). So, to help you avoid these no-nos and hit all the yes-yeses, Refinery29 editors Annie Georgia Greenberg and Kristian Laliberte are schooling you on all the dos and don'ts with a lil' video tutorial. Turn up the volume and press play. We're calling it tentiquette (tent etiquette) or rather #tentiquette, and trust us, it's trending. No #fashionworldproblems here.
