It's pretty well known that wearing black in the summer is a bad idea. Wearing black during the summertime is guaranteed to make you feel run down and hot. This is because black clothing is known to absorb more heat (via NPR). When you're absorbing that heat, you're going to feel sweaty, sluggish, and overall bad. This can totally ruin your day or night out, and can even cause things like heatstroke if you're out in the sun and heat for too long (via Mayo Clinic). 

Wearing lighter colors is a better idea, but you also want to avoid things that are too light like gray. Gray is known to be the "least forgiving" color during the summer. As Simplemost points out, light and dark gray shirts and even dresses show the most sweat stains during the summertime months. The last thing you want is to be out with friends taking pictures and get tagged in a photo where you have huge, wet sweat stains on your shirt! 

The best color for the summer? White. This light and breezy shade doesn't showcase sweat or cause you to overheat (via Leaf.tv). Win!
