Would love to know what others feel they've learned!
Trying to enumerate a few things I've learned:
Bookending
Being mindful of the effect of light hair with dark winter outfits and trying to do something about that. (When looking in a mirror I tend to cut my OWN head off, just considering the outfit from the neck down; photos really help with this, and that is why I prefer WIWs to include people's faces and heads.)
The A line is not necessarily my best skirt!
What jackets work with what bottoms.
I CAN wear a high vamp shoe with dresses if I tone my tights and skirts to it.
