We all know a couple years back when Paris and Nicole we're BFF's that they were running around Hollywood with the Jackie O 60's big Sunglasses.  Now, I look around and although I'm still seeing those sunglasses I'm seeing more of the Erik Estrada look of the 70's, you know the Ray Ban Aviator sunglasses that Usher wears all the time.  Let me emphasize on all the time, which of course we all know he got it from his all time hero the legendary icon Michael Jackson.  However, I find that I'm am partial to both looks myself.  On Ms. Richie, well that's a different story her face is just too small for glasses that big.  The good news is we have a vast variety to choose from.  But I have to ask just one question, why do they wear their sunglasses at night........?
