Hm, I can't say that this hit the nail on the head for me.
I DEFINITELY care about how I look. I won't even go to the grocery store without makeup. But... I am pretty minimalist; I generally only wear tinted moisturizer, mascara, and eye liner. My hair for awhile now has been long and layered, which is intentional so that I can wear it natural with next to no effort and still look good (I aim for wavy usually). I used to straighten my hair daily though and put effort into getting it just so. As for haircuts, I let myself go waaaaay too long. Always have been like that. I used to do 1 haircut a year, and was doing it myself for awhile. My sense of style is not avant garde and I am in fact really turned off by the overly artsy/high end in appearance. I correlate that look to arrogance and materialism which are my top 2 turn offs. I generally approve of people who rock a unique rebellious look though - just can't stand that upper class haute couture look. As my me, I like to look sexy-casual. I like to show off my body through fit and will not wear ill-fitting clothes. Even lounging at home in front of my boyfriends, I like to look cute or sexy so I make sure the t-shirts I wear fit well, whether baggy or fitted. I don't want to look like a stick person in a giant boxy men's shirt; long and lean is the way to go. I describe my look as timeless with a hint of boho and rebel. I wear a lot of black, blue, and grey. I avoid bright bold colors but I have to because I am very fair skinned with pink undertones, so warm colors are out of the question. I don't care much for accessories, but I have a collection of probably more than 20 scarves that I never wear

I don't wear my jewelry ever either, and I change out my handbags only seasonally 2-3 times a years. I pride myself on looking good but being practical and thrifty; 90% or more of my clothes are bought second hand, and 99% of everything new is bought on sale. I grew up very poor, so no doubt that has probably influenced how I feel about money and practicality. I generally dress to match my mood, and I used to match my undies to my camis everyday. Boots make me feel sexy and powerful and have way too much influence over how I feel for the day and the energy I emit, lol. I don't iron my clothes and am not organized enough to actually put my fucking laundry away, so piles around my room or in baskets are common (I have 2 full-sized closets but no dresser. I have like... 10 things hanging up, lol). I do have ADHD though which makes me less organized and I generally don't care for silly tasks like folding clothes. I won't wear holey things unless it's jeans and it looks rebel or grungey in a good way.
Basically, I care a lot but also not enough

The paradox continues...
Side note: I love the videos by Thinker on YouTube, whom she referred to. Thinker is a great visual of what an INFJ looks like when trying to communicate thoughts to others and is also why I will never make a video, lol. Beautiful bohemian woman, btw.
