Love her, hate her (hate her some more when she borrows your new top before you've even gotten a chance to wear it), a sister is a friend for life. To celebrate that special bond and Sisters Day, see 35 adorable photos of famous siblings palling around.
Two moods: laughing on a railing...
And being tired of your shit while wearing cool hats.
The sisters that don purple wigs together...
At least have some more protection against getting slimed.
THEY HAVE THE SAME SMILE.
You know they planned their outfits to fit the "Urban Cowboy" theme down to the belt buckle.
When you do an impromptu fashion shoot with her and it comes out looking like a luxury ad campaign.
The head tilt. You know what I'm talking about.

Peace signs? Or failed bunny ears?
The head tilt, a variation.
Okay, but what vile concoctions did they actually make one another drink as kids?
You can't even tell where one begins and the other ends.
How you think you look when you're dancing.
Ah, 2005. We miss you.
The funny thing about sisters is you can take a nice photo (like this) one second and the very next be at each others' throats.
Tag yourself. (I'm Cara.)
Ali's facial expression: totally plotting to borrow Lindsay's Balmain dress.

Using your sister as a prop: brilliant.
Sandwiched between her mom and sister.
The one pinched the other. JK, but plausible.
She'll never hesitate to tell you your hair's wonky, that's for sure.
All sorts of '60s fabulousness.
Home, a bar, front row at Saint Laurent—as long as you're together, what's the difference?
Really going in on the twin thing.
The came a death match for the last slice.
RT if your sister is the only one who can make you laugh like this.
