We caught Lindsay and her good buddy Samantha Ronson, er, swinging by YSL's boutique on Rodeo Drive yesterday afternoon. Lindsay certainly wasn't too shy about showing off her braless chest, either - seriously, you can practically see those things jiggling around in the stills!

Hey, we're not complaining...

... and we doubt Sam is, either!
