Your professional style is of the utmost importance as you climb the career ladder. In the summer months it can be particularly difficult to strike a professional balance while staying cool outdoors, and not freezing in the office.
For that reason, I am a big fan of classic sheath dresses with a blazer or jacket. The layering gives you the ability to stay warm in cold office environments, in addition to allowing you to mix and match different jacket/dress combos to expand your wardrobe. Investing in a couple of sheath dresses and jackets that fit perfectly will lift your confidence and exude professionalism.
Here are some of my current faves!
