I've been wearing a lot of purple these days as well as combinations of greens and light blues. I like black too, but I feel like all black is kind of dull. A black graphic tee or black striped shirt with some black skinny jeans and colorful sneakers though is a look. I also have this black sweater I really like that's covered with rainbow glitter. I like a bit of jewelry too, which could be a choker, a pendant, pins, a watch-all that jazz.
Does it tell about type, meh. Black makes me think of ISxPs, but an ESFJ could be wearing all black too, you never know. Might be their favorite color. I guess I'm not too stereotypically 4 since I'm cringing at the thought of all black. I'm not sure what type my style is cause it's so varied(which could be 9), but I think attitudes towards fashion can be indicators of type. I think any type could be fashionable if they wanna be, but I think my Fi plays into my fashion sense cause I do try express myself through fashion. That could be something as simple as wearing merch of my favorite shows, or going for certain themes in my clothes(like punkish or Victorian). I've been told I have mismatched clothes by some people, but eh, I don't see it. My clothing style's been dubbed everything from Punky Brewster to punk to even old ladyish(cause of black sparkly shirts). Nowadays, I'd say it's more a nerdy chic or bohemian.
