Keep your clothes loose. The looser, the better. The less fabric you have actually touching your body, the cooler you will be. Believe it or not, a loose and and flowing maxi dress will keep you cooler than a pair of shorts and a skin tight tank.
Avoid flimsy fabrics if you don’t want your clothes to stick to your body.Lightweight fabrics are great for hot weather, but they need to have a little structure so that they don’t just cling to your body the second you start to sweat.
Layer with open-weave knits. That way you will be able to feel every glorious, cooling breeze.
Choose clothes in natural fabrics. Cotton, for instance, is much more breathable than polyester or rayon. It’s also better at absorbing sweat and dries faster, which means you won’t feel sweaty as long as you would if your clothes were made of synthetic fabric
Bring shade with you wherever you go by wearing a wide-brimmed hat or carrying a lightweight, woven scarf in your bag. Drape the scarf over your shoulders or head whenever you feel like you are getting a bit too much sun. It’s so lightweight that you’ll barely feel it. Promise.
Leave your backpack at home in favour of a small cross body or tote. The last thing you want on a hot day is a huge backpack stuck to your back, making you sweat. Take this opportunity to clean out your bag and get back to basics, since the less stuff you carry around, the less you will exert yourself, and the less sweaty you will become as a result.
Cover up to protect your skin from the sun and keep cool. Direct sunlight not only damages your skin, it raises your body temperature.
