In a few days I'm going to an amusement park, it has lots of rollercoasters and the normal stuff you expect in an amusement park. The day I'm going it's gonna be 28 degrees. I don't wanna wear shorts, so is leggings and a t-shirt to warm? Or is it fine? And also is it appropriate for an amusement park?
If it's 28 degrees Celsius that would be fine, it may be a little warm but the worst case scenario you would roll up the hem. If it's 28 degrees Fahrenheit you may want to dress a little warmer, perhaps bring a sweatshirt. I believe the outfit would be appropriate for an amusement park.
Its certainly appropriate. Whether the legging is too hot will depend on two things: the color (wear a light color to reflect sunlight) and your body (does it heat up quickly or not). Otherwise, I would consider a short if you don't want to ruine your day by being too hot and sweaty.
