L'vow Victorian Real Natural Feather Shrug Shawl Shoulder Wrap Cape Gothic Collar

If it is synthetic, why does it say it’s from a rooster? i want something completely synthetic. can i have a real straight answer?

Is this machine washable ?

Would this fit most people or is it small?

Is there one with white on white? The black belt is way overpowering for my costume uses. Looking for just a white on white option?
