Reddit mentions of Magicfour product

I bought some cotton dust masks off of amazon a few years ago ... the cute kind you usually see Asian girls wearing in like animes and stuff.

These are the ones I actually bought; though sadly they're not available anymore

Closest thing I can find on amazon now is these ones; not as cute in my opinion but they're an option.

Depending on how fast you need them could always look on other sites for things like that. Etsy has some that might work, or aliexpress has a bunch of the cuter ones for example but shipping usually takes a couple months.

Could also look for like a face veil from a belly dancing costume? They tend to be a bit transparent but a dark enough color may work. A nice scarf may also work; but you'd have to build an outfit around those items I think instead of them just being an accessory - in other words a belly dancing veil would look weird on a normal outfit, etc. That's why I originally went with the cute cotton dust masks.
