My dear, em. Good observation.
THERE IS NO ONE WAY TO BE STYLISH. Style starts and ends with a strong sense of self, and THAT'S the key to creating, maintaining and evolving a style that makes you feel fabulous.
One of the most important aspects about fashion and style is to appreciate a look on someone else that is very different to your own. You are not them and they are not you. Needs and sartorial preferences are different for good reason. We can be inspired by another person's style because it might spark something off. Then we MAKE IT OUR OWN.
I have hundreds of clients, and there are similarities between some, but no one looks exactly the same. No one wants to dress exactly the way I do and that's a good thing! They are all encouraged to make their look PERSONAL. I love their look FOR THEM, and not for me.
So keep poison eye to a minimum, keep an open mind, and have empathy and understanding for another who wants to dress and feel fabulous their way.
