We're not sure if this is outerwear or PJs, but we love it!

Miley tweeted the selfies above and wrote, "@chanel #1z #mostprizedpossession ... Don't hate. Appreciate. #Chanel1Z."

We'll be honest -- we kinda miss Miley's longer locks sometimes, but one person who is a huge fan of her short blonde 'do is her future sister-in-law, Elsa Pataky.

"Hers is really short," Pataky said in a recent chat with People. "It's funny, we talked about it doing it some time ago, and [we were] like, who's gonna do it first? And she cut it off and I was like, 'I'm not doing it.' [Then] I was like, 'Just do it!' Now, of course, they compare us. But she's going shorter and shorter and shorter – which I love."
