Jennifer Aniston, Justin Theroux New York tee shirt jeans

He might have had a sleepover at Jen's house, but you would think he has a change of clothes there at this point!

Justin Theroux was spotted walking along the streets of N.Y.C. on Sunday, and the actor was in the same outfit he wore the previous evening for date night with fiancee Jennifer Aniston. Maybe the Wanderlust star was on his way back to his own pad to switch ensembles?

Then again, the screenwriter pretty much wears a uniform of jeans, biker boots, and white T-shirts, so maybe this is the signature look his lady love prefers!
