Sienna Miller on Friday's Tonight Show Show with Jimmy Fallon, wearing a striped dress by Monse. I feel like everyone is wearing this designer this month! 

This has been Lady Gaga's week! She has been looking great promoting her starring roll on American Horror Story. And last night she looked so stunning on The Tonight Show with Jimmy Fallon in this glamorous shimmering dress by Monse with Brian Atwood heels!
