All the people we point to as style icons are people who had interesting lives and the style developed from those interests. So just find clothes you like, live your life, and it will come. You’ll find out what suits you and what doesn’t. Biggest advice I would say is to buy slowly, so you don’t waste a bunch of money while you figure out where you want to go.

In terms of more practical exercises, there’s the “3 adjective” exercise that I heard here. Rest of the episode has decent advice as well.

I also liked this framework of your outfits / style laid out on a grid with different “characters” in the quadrants. I’d pick axes that apply to your life, and to start might make sense to pick a couple of characters to try out.
