A phenomenon which makes people think you wear a particular item of clothing all the time because you are tagged wearing it a lot.

This is even if the photos were from several separate nights which were months apart but they were the only photos you were tagged in.
I was going to wear that black t-shirt tonight, but i'm wearing it in my recent Facebook photos, so it's a bit Facebook-worn.
