The Maroon 5 front-man, clad in a pair of destructed skinny jeans, was joined for some pictures on the red carpet by his band mate, James Valentine. James was wearing a denim jacket paired with a pair of black jeans.
Adam Levine’s jeans seem to be comfy enough for him to jump and move on the stage, but I don’t think they were stretch jeans. They are a medium blue wash with rips at the knees and some fading all along the legs. The style is a straight slim fit with a bit of a lower crotch.
