Posh and Pretty seems to be a fitting phrase that describes the Best Dressed Celebrity Style Pooh-Bahs of the week! Amber Riley looked great in cobalt blue, while Olivia Palmero and Jessica Alba looked prim and chic in black and white – with Jessica adding a hint of pink. I also love how Maria Sharapova took a simple sparkling top in a casual yet, dressed up direction. And, Lupita…I mean geesh, the woman never seems to have a bad outfit day! Last, but certainly not least was Rihanna in a Euro glam look, which also had a bit of laid back cool appeal that only she can pull off. Which of theses looks is your favorite?
