As a Northerner living in Charleston, South Carolina, the heat is one thing I have yet to get used to. Sure, summers on the East Coast are hot, but the southern heat is no joke with heat indexes reaching up to 115 degrees (yikes). So what do you wear when it's that hot out? These writer-approved clothes that are stylish and cooling, of course. When temperatures reach over 90 degrees, you want items that are breezy, lightweight and cooling. That's why I opt for tank tops, dresses and pants with breathable materials like airy linen and soft cotton.
