4chan in general is dying because there are so many more options online to discuss interests. Even the young friendless virgins are on Instagram and TikTok these days so the niche 4chan carved is being occupied by more obvious options. The entire website is dying, not just particular boards, because literally every board you visit talks about how their board in particular is dying, talking about the glory days from 2008-2016.
It kind of sucks because fashion is at an all time high as far as popularity and acceptance in the mainstream, meanwhile this board is essentially dead, and fashion discussion outside of 4chan is normie, basic, and boring. I want to talk about fashion with regular ass people, not within the comments of some influencer, and I sure as hell don't want my name attached because then ego is a factor and I can't be blissfully honest. Sometimes I look around for better options and genuine, general discussion is not a thing.
