Keep your clothes loose
In the summertime, the motto to follow with your clothing is - the looser, the better! The less fabric you have touching your body, the cooler you will be. Believe it or not, a loose and free flowing maxi dress will keep you cooler than a pair of shorts and a skintight tank.
Skip the padded bra in favor of a soft, unlined bralette
Three inches of foam padding + a hot summer day = major boob sweat. It’s true! Ladies, loose the padded bra this summer and stay cool with a soft bra sans the lining. It will make all the difference to your breathing and body temperature.
Choose clothes in natural fabrics
Cotton, for instance, is much more breathable than polyester or rayon. It is also better at absorbing sweat and dries faster, which means you won't feel sweaty like you would if your clothes were made of synthetic fabric. A hat will keep the sun away from your precious skin! And 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.
Wear unlined jackets, skirts, and dresses
Not only is lining adding one more layer between your skin and the air, it tends to often be synthetic, which mean it won't breathe well and will leave you feeling like you are walking around inside your own private sauna. Ditch the lining this summer!
Leave your backpack at home in favor of a small crossbody 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.
Wear as little jewelry as possible
Earrings are fine because they don't really touch much of your skin, but necklaces, bracelets, and rings can often be more trouble than they're worth once temperatures start to rise. Lightweight chains stick to your skin, heavy necklaces trap your shirt against your chest, metals get hot, and bracelets cover your wrists, which are a major cooling point on your body.
