Captain America (Chris Evans) wears 6 different uniforms in the MCU. In Avengers Endgame he uses again 3 versions. The coolest one, from The Winter Soldier he puts on in the very beginning to go find Thanos. The classic from the 2012 Avengers he uses during the Time Heist which generates the hilarious comment: "This is America's Ass". During the final Battle he wears the one from Age of Ultron. He also keeps nearly the same civilian clothes: the flannels (he uses in The Avengers), the leather jacket, the tight shirts (like in Age of Ultron), the white undershirt (same in Winter Soldier) and the super stylish classic black sweter he wears in Civil War. We never see again his jaw dropping bare chest like in The First Avenger though. One reason might be, how difficult it is to conceal his tattoos. Chris Evans has several on his chest and arms. He said that the makeup takes an extra hour just to hide them.
