I totally agree with you about having more gothic clothes in the game, I love making goth sims!
I only had casual gothic clothing in mind as well as gothic lolita dresses, gothic harajuku fashion and just more victorian era clothing, I think? https://contestimg.wish.com/api/webimage/5cfcd35c1c333d42623ea769-large.jpg?cache_buster=2dbed2533a1701c8983d547e904afc71

I also think it'd be cute if they released a pack of gothic vs angelic or lighter colored versions of the clothes, that way people who aren't goths won't feel excluded.
