India, May 14 -- Catching flights is all fun and games until you realise there is a hidden dress code many travellers aren't aware of. Recently, YouTuber and flight attendant Barbara Bacilieri went viral after she shared tips on what not to wear to avoid getting kicked off a plane. Airlines won't always tell you this, but there's a hidden dress code, and breaking it can get you denied boarding, delayed at security or put in danger during emergency. Heels can pop the evacuation slide. Flight attendants are trained to remove passengers' shoes, especially high heels or thick boots during an emergency evacuation. This is because heels can poke a hole in the inflatable slide, which will cause it to lose air. Even metal accessories, jewellery or belt buckles can do the same. Barbara also advised against mini dresses, skirts, shorts and crop tops when travelling. She said: "Sure, they might look cute on Instagram, but during an evacuation, they're a recipe for burned thighs and scraped skin. Sliding down that inflatable ramp with your skin exposed. She also recounted a situation when two women were removed from a flight for wearing crop tops. They had removed their sweaters as they were feeling hot, and when they asked about the official policy, they were kicked off the plane. Another think that one shouldn't do when flying is to cosplay as a pilot or flight attendant, even as a prank. Barbara shared that "wearing a pilot or flight attendant costume might sound fun, but in an emergency, it could cause serious confusion". HTC...
