Twin Permissionals

Is it bad to say that I'm a little jealous of the relationship these two adorable girls have? I have to laugh because at times they like to dress and look alike and when they do, they call it "Twin Permissionals", whatever that means exactly I am uncertain. Skye did both their hair the same, I am surprised at how long it was. This was taken at the beginning of the holiday season in their matching Christmas PJ's.
