As long as the goods are covered there is nothing to worry about. A short skirt provides best freedom of movement, cooler than shorts, and looks better. It's the most comfortable thing you can wear!

While it is technically "okay" to wear a skirt on a roller coaster, it is generally discouraged for practical and modesty reasons. High-speed coasters involve intense winds and rapid changes in orientation that can easily cause a skirt to blow upward, potentially leading to embarrassing "wardrobe malfunctions." Furthermore, many modern coasters use "over-the-shoulder" restraints or "lap bars" that include a raised "hump" between the legs for safety; sitting on these in a skirt can be physically uncomfortable or visually revealing. If you choose to wear a skirt, the best strategy is to wear athletic shorts or leggings underneath (the "Skort" approach) to maintain coverage. Avoid long, flowy maxi skirts, as the loose fabric can pose a safety risk if it gets caught in moving parts or the boarding gates. For the best experience, choose a knee-length, more fitted skirt made of a heavier fabric, or stick to trousers or shorts to ensure you can focus on the thrills rather than managing your hemline during a 70 mph drop.
