Take note, people! THIS is how you do a wedding!

Kim and Kanye arrived to their nanny's wedding this afternoon -- yes, their NANNY'S wedding -- in Simi Valley, just north of LA, looking SO on point it hurt!

Kim wore separates -- a tight, cleavage-exposing halter with matching floor-length body-con skirt, while Kanye stuck with a traditional black suit. Kourtney chose a wide-legged jumpsuit, cut to the navel. Little Penelope snoozed on her way in, while North was excited to be a flower girl. So cute!
