Like Ledonna my style seems to make major changes every 5-10 years. Right now I am going through a more practical, classic phase. Before, I'd say 2011-2016, I was all about enjoying trends and embracing most of them enthusiastically.
As I age I find a classic look is more flattering. I am figuring out the accent notes I want to incorporate. As well as, which type of classic dressing that is most "me". I have a feel for modern classic as well as avant garde classic. I remember reading a quote by Marc Jacobs saying that women shouldn't have to commit to just one signature style. That they should enjoy expressing themselves in multiple styles.
Of course there may just be a business motive behind that thought.
