I find blazers a must-have piece for any business woman. It gives a formal touch to your look and it makes you feel a bit more powerful (this is my personal opinion, of course). Combine it with a bodycon dress for an important meeting of with a pair of trousers for a casual office day and you will always inspire professionalism.
Add a pair of good flounces to a good blazer like this one from Shein and then you are not only profesional but also a fashion icon. Because professionalism does not need to be boring.
