We love Beyonce's smile and we can't get enough of the vacation pics she posts on Instagram and Tumblr, but why is she so obsessed with this outfit?! And herself, for that matter...

Yesterday the R&B superstar posted a number of photos of herself in this $700 Stella Jean plaid skirt, and she also uploaded a few clips of herself shaking it to D.R.A.M.'s song "Cha Cha." You know the meme, "You have the same amount of hours in a day as Beyonce?" We saw a mug with that saying on it a while ago and definitely got a bang out of it, but we have to wonder what else Bey is doing all day if she's just posting Instagram selfies...
