Never pass out drunk at a Paris Hilton
party ... because her immature friends will dress you up in embarrassing clothes and then take photos of you.
The above pic was snapped at Paris' 4th of July bash in Malibu ... and as you can see, some poor schmuck obviously had a little too much to drink and fell asleep on a beach chair.
Thankfully, Paris and her friends let him snooze peacefully until he woke up. Just kidding, they dressed him up in a bikini top and gave him a purse and sunglasses. Then took photos.
As far as we know, no markers were involved ... those are this guy's actual tattoos ... but still, HILARIOUS.
Except not really.
