Kanye West Get Your Autograph Pen Away from My Priceless White Sweater

NEVER APPROACH KANYE WEST WITH A PEN -- especially if he's wearing a fancy sweater -- because after Yeezy's reaction in Paris this evening, you might as well be waving a knife in his face.

Kanye was leaving dinner moments ago when an autograph seeker asked the rapper for some love -- holding out a pen ... and a sneaker to sign.

The pen came within inches of Kanye's pristine white sweater -- and Yeezy nearly lost it.

You gotta see it. Ye's reaction is almost worth as much as his threads.
