Chris Evans mustache always amazes me. Two completely different styles that in and of the stache itself, looks great. In the second photo, to me, there is something wrong with the look. I think it is the intense height of his hairstyle that results in making his face look much longer and his jaw narrow and weak. That somehow takes away from the hotness of the extended chevron stache he's sporting. I can't help but compare the seemingly perfect balance of the first picture to the second. His face and stache look so balanced. Personally, I think he looks better with the chevron stache, he just needs to change the hairstyle.
Still a great example of when the stache makes him.
