Most definately the hairbow wig, the crown, and the surgical mask. I don't feel clothing really can be a status symbol, because most people use QR clothing. But I feel like everyone has the hairbow wig, and if not then they're wearing a crown xD
In fairness though, I think it's more that these items are adorable and go with most girly outfits, more than it's a status thing. I have some of my themed mule villagers wearing those, more because they're cute than anything.
I don't understand the surgical mask/eye patch thing though. But I've never been into goth culture, or Asian style (I think I've seen pictures of Asian girls wearing themed surgical masks as a fashion statement...? -is oblivious-)
