We hope you plan on cracking open the bubbly today in celebration of our First Lady’s 51st birthday. Last year, she celebrated her 50th with the best birthday party ever (Beyoncé was in attendance). We’ve since forgiven her for not inviting us to that fête (we’re really good at parties). How can we stay mad at someone who is smart, beautiful, driven and looks consistently fabulous? Michelle Obama spent last year serving us even more fabulous outfits, and we wager she will be just as fierce this year. So to honor the FLOTUS on her birthday, here are eight times she absolutely slayed us with her impeccable style in 2014.
