"Depends on the kind of fun, honestly," Lea said. "Obviously you don't want to be too hot or cold, so especially if you're going to be outside, factoring in weather is important. For beach fun, it usually involves wearing light-weight clothing that won't get in the way if you do things like swimming or playing beach-related sports like volleyball. Most people go with a swimsuit and sandals, along with maybe a wrap or t-shirt and sun hat."
