The "We Own the Night" actress looked casual cute as she hit up a local boutique - leaving a short while later with her newly purchased flower vase.
The sighting comes just after Miss Mendes chatted with W magazine about her openness to stripping down for films.
She tells, "I've never had a problem with nudity, but I don’t put it out there without a reason. I'm not an exhibitionist. But, honestly, for my art I'll do anything almost. I'll go there."
"I know I walk a fine line between being a respected actor and being what they call a sex symbol. But I've never felt objectified. Nothing you see me do is an accident. I might act like it's an accident but the opposite is true. I'm incredibly calculated when it comes to my career."
