OH MY GOSH! Those shades are hot. I just want to start by saying that Robert Downey Jr. wears some of the coolest shades and these seem to be his favorite pair. I found quite a few different images with Robert wearing this same pair of sunglasses
. It was obvious that the photos were not taken at the same event. I was able to identify that this model is the Giorgio Armani 421/s Sunglasses
. If you are looking for something to rock on your red carpet try the Anne Klein Sunglasses AK4117 (AK4117-334-44-5616)
I hope this helps.
