Kristen Stewart in Marios Schwab & Vivienne Westwood | “Snow White and the Huntsman” Mexico City Photocall

Kristen Stewart and her “Snow White and the Huntsman” costar Sam Claflin made the long trip from Madrid last night to promote their movie in Mexico City today.

The 22-year-old actress arrived for a press conference and photocall wearing yet another menswear-inspired look! K.Stew is killing it on this press tour, you guys! All of these trousers, blazers and button-downs are hitting some serious high notes with me.

Today she wore dark gray cotton-twill “Sailor” skinny trousers from the “Anglomania” collection by Vivienne Westwood. These pants are really unique as they feature angled out slant pockets. Kristen made the style her own by folding down the pockets and rolling the legs into a cuffed look.

She bared a little midriff with a Fall 2010 sleeveless button-down white top by designer Marios Schwab. You may remember Kristen wearing a couple of his dresses last year, including her hand printing ceremony at Grauman’s Chinese Theatre.

Kristen has all of the nay-sayers so fooled — you underestimate her!

She may have been keeping her shoes pretty basic due to a recent injury, but when K.Stew changes it up — she knocks you out! First with those blue blade pumps and today with the ultra-hot Christian Louboutin “Un Bout” fluro yellow pumps. These neon lovelies are a hit with Hollywood right now as they feature sexy clear PVC elements on the sides.

Kristen accessorized with a neon and gold BaubleBar ID bracelet and a Anita Kogold bracelet.

With smokey eyes, a hot pink glossy pout and a mane of tousled waves — her look was complete.

What did you think of Kristen’s belly-baring trouser look today?
