Troian Bellisario (Spencer) has a poise and maturity about her, so we think the ‘40s-esque style that she recently rocked is perfectly fitting.

The Pretty Little Liars star was seen with her co-star Shay Mitchell (Emily) on set of Extra in LA, wearing a pleated patterned skirt, a white collared top with shoulder embellishments, and brown lace-up boots. The brunette actress even showed off a pinned-up, short hairdo, really channeling her inner vintage.

And aside from just looking stylish on set, the Little Liars’ outfit also served a great cause. The girls’ purple outfits (Shay wore a purple dress and Troian wore a purple ribbon pin) were for Spirit Day — a day where Americans wear purple to take a stand against bullying for LGBT youth.

What do you think of Troian's throwback look? Is it too outdated for your taste, or do you find it fresh and trendy? Let us know in the buttons below.
