Believe me, your question is brilliant, and by far stupid 😂
Hmm. Before my studies, I had to get employed by a company for backing, and I wore a checkered shirt, dark jeans and my good shoes to the interview. Apparently it worked...
During my studies, I wore quite casual clothes, so when I had my interview afterwards, everyone knew me already and I didn't wear anything special.
During the past two years, though, I started separating stuff I would wear at home and office clothing (mainly because my private life is not compatible with a professional demeanor). At the moment, I use a white shirt, black pants and black sneakers with long black socks. No necktie, that thing is out at Bosch. My mother gave me a black blazer for Christmas, so I will probably give it a try after vacation. I'd go to anything with that: the office, official meetings and interviews. It looks good, professional, conservative and I frequently get complimented by all kinds of people 😉
I have been in a few interviews on the other side of the table as advisor, though, and I have seen different people with different get-ups. Imho, the clothing should reflect what you think is acceptable for the position you apply for. If it's an office job with only little customer contact, casual clothes will do the trick. If you want to be an advisor who has to travel to other companies, try to go for a very neutral, professional look. Bonus for matching the style of your future co-workers.
it also being a remote web developer position
Since it's remote, I would go for casual clothing. People know that you are working from home, so that's what they might expect to see. Keep your fancy stuff for when you visit the office. I never really thought a lot about dress vs skirt vs trousers, though, however I know that most business women over here go for trousers. Don't forget that you have to be comfortable with what you wear, though, too!
