So I'm not sure about where you are in the world, but here along most of the eastern seaboard, it is a scorcher! 35 degrees Celsius/100 degrees Fahrenheit?? I am not used to these temperatures. Staying cool has definitely been a hard task.
What have we learned from this past week of record-breaking heats? Wear loose-fitted clothing. Avoid dark colours. But really, aside from that, there's not much else one can do. I think I've exhausted my wardrobe trying to find something appropriate to wear to work while trying to keep cool, which is an additional obstacle in the heat. Midi-skirts and shirts made of light materials? Yes, please. The same should be applied to shorts for the workplace- keep the length reasonable. And if you do opt for a tank or halter, I'd bring a cardigan or pashmina to the office, especially if you have air conditioning on full blast.
But folks, there's also one more thing to keep in mind- do keep it classy. I know it's hot, but I'm really not interested in seeing excessive cleavage or the bottom of a butt cheek.
Instead, opt for cute numbers that will maximize coolness without being trashy:
