When it's sweltering outside, but you need to look pulled together and professional, remember this: tailored pieces in cotton and linen blends are your friends. The key is to refrain from wearing anything too tight; you want to make sure your clothing has a little give so you can move easily and not trap heat in your clothes. A solid-colored one-button jacket is a great staple to have on hand, though a floral or striped version will work too. Wear it over a cotton t-shirt or silky shell and style with a knife-pleat skirt for a polished-yet-cool ensemble. Alternatively you could wear a structured vest with a crisp button-up and relaxed or slouchy tapered trousers. If you're more of a dress girl or simply like an uncomplicated outfit, I have an idea for you too! A long-sleeve shirtdress is perfect for work, especially in a personality-filled print like paisley. A breezy silk dress is another excellent option; just be sure to style it with a lightweight cardigan for the air-conditioned office. Finally, stock up on silky shells and camis in dark colors. They don't show sweat marks, which is invaluable in hot climates!
