Beyonce's baby sister Solange looked like she forgot something when she walked out the door to attend the premiere of Bey's 'Life Is But a Dream' doc in NYC last night (Feb. 12).

Keys? Nope. Smartphone? Negative. Lip gloss? Got it. As you can see, Solange, who upstaged her sister in an emerald green gown at the Grammys earlier this week, forgot her pants.

She's wearing what looks like a crisp white button down -- and little else.

Yes, it's sexy. It's a mini. It's geometric. It's winter white. It shows off her killer gams. But it's also missing a little something.

We applaud how Solange played with volume on the top and bottom, with her mega bangin' black afro and those sexy, skinny, strappy heels. The red lips and nail polish provided a gorgeous contrast. But it looks like she slept over at her boyfriend's, threw on one of his dress shirts and headed to the soiree.

Overall, the styling and the length felt sloppy, especially after Sunday's showing where she wowed us. Sol dressed as though she was on her way to a pajama party, not a red carpet premiere. So much for consistency.
