Interesting thread! I am an ENFP on the Keirsey temperament sorter, which I've studied to death for years. It's been my understanding that there are slight differences between the Meyers-Briggs and Keirsey scales: Meyers-Briggs will tell you more about how you present yourself at work, which can be different than in your personal life.
On Keirsey I am 100% ENFP across the board, making me a flamin' Champion. How does this affect the way I dress? I would say:
1) as an extrovert, I am comfortable drawing attention to myself, and I don't hesitate wearing bold clothing.
2) as a champion, I love talking with people about fashion and clothes and if I love a particular shoe or brand or other item, I will let the world know.
3) I am a creature of reinvention. Always striving for self-actualization. In fashion terms, this means constantly trying to dress more and more stylish, and adopting new trends.
4) Idealists also tend to be the "chameleons" of the four types. We are apt to change ourselves/bend ourselves according to those who are around us most. The way this translates in fashion is about trends but also about wanting to dress in a way that fits in with the occasion. This is very true for me - the first question I ask when going out somewhere with friends is "what are you wearing" and I get uncomfortable if I show up somewhere and I've missed the mark and overdressed or underdressed. (A little overdressed is always okay)
5) Idealists are all about authenticity. We strive to be authentic and when we are not, we get unbalanced and feel stressed. In fashion sense, there are numerous ways this translates. The first that comes to mind for me is that feeling of unease when a certain outfit just doesn't work for one reason or another. Those mornings when you rip apart the closet trying on one outfit after the next and nothing "feels" right. Or when I might like the idea of a trend in theory, but when I try it on, I get that "this just isn't ME" feeling.
6) as an idealist, I am quite skilled in sizing people up. I have great intuition about people. Mostly it's about picking up their microexpressions, but how one dresses can be a factor in this. Also I can be pretty good at picking out clothes that work for other people. When I go shopping with my mom, or teens, or friends, I always seem to be able to spot that one item that is perfect for them.
It does not surprise me that Angie is also an idealist. I suspect most fashion stylists are. Especially also because Idealists make the best diplomats!
