Most of us go for a cute little dress when attending holiday parties–it is a tried-and-true look. Dress + Tights + Heels/Boots = All kinds of prettiness! I am rethinking my formula after looking at how adorable Natalie Portman looks with her trousers and blouse. You could easily do a less cropped or skinny pant if you want, but I just love the stovepipe trousers paired with heels and a sexier top. The shape is flattering (especially with the nipped in waist!) and formal enough for a party. I may have to try to copy this outfit at some point, even if it is inevitable that I will look 98% less cute than Ms. Portman.
