- "We've made some modifications to the uniform. I had a little design input."
"The uniform? Aren't the stars and stripes a little... old fashioned?"
"With everything that's happening, the things that are about to come to light, people might just need a little old fashioned."
- ―Phil Coulson and Steve Rogers
Captain America's Uniform were sets of uniforms used by Captain Steve Rogers which served as his outfit during his superhero exploits. Fitting in with his identity as Captain America, each costume had a design representative of America, including his stealth costume, which had a more subtle stars and stripes motif.
Shortly following undergoing the procedure that turned him into a super soldier, Steve Rogers was denied the chance to serve on the battlefields of World War II. Instead, he was offered and accepted a position working with the USO, performing in stage shows to sell war bonds to promote the war. As part of his performance the USO created the image and identity of Captain America to serve as a mascot and symbol of nationalistic pride for the American people to rally behind and increase support for the war-front. Captain Rogers wore this costume in a number of stage shows in cities across America, as well as in a number of other images and iconography, including a number of fictionalized film reels of "Captain America" leading troops in the war, to help increase morale. 
Original Field Uniform
Strategic Scientific Reserve Field UniformHoward Stark. It was made with a shield of vibranium for Captain America to protect himself from gunfire. Captain America used the shield and wore the uniform in all of his attacks on enemy facilities and other missions. He had the shield with him when he crashed in the Arctic Circle and was frozen. Nearly 70 years later, S.H.I.E.L.D. stumbled across the crash site of Captain America's plane. He was found alive, and he had the suit.

STRIKE Stealth Uniform
Captain America's fourth uniform was a stealth uniform, given to him by S.H.I.E.L.D. for secret missions. The suit was a navy blue, utilitarian-style suit with a Kevlar-based ballistic component that could protect Captain America but at the same time function like a military black-ops uniform. It was used to retake command of the Lemurian Star and to escape from the Triskelion.

Second Avengers Uniform
Third Avengers Uniform
Captain America adopted a modified version of his second Avengers uniform as the leader of a new team of Avengers. He later removed the Avengers logos on his shoulders following the ratification of the Sokovia Accords. This version of the uniform dispensed with the electromagnets, re-adopting the more traditional straps.
After the Battle at the HYDRA Siberian Facility, Steve Rogers went on the run. While in hiding, he removed the star from the center of his uniform and disposed of his helmet. Eventually, the entire suit was dirtied into a slightly darker color with more rips around the center, exposing the chain mail/linked scales underneath the outfit.
Fourth Avengers Uniform
Five years after the Snap, Steve Rogers used a much newer uniform that resembled his last one, which had the chain mail/linked scales on it; however, the scales were now exposed, unlike the last one, where they were hidden under the outfit. He later used it during the attack on the New Avengers Facility and their final battle against Thanos and his army.
- According to Paddy Whitaker in The Art of Captain America: The First Avenger, the fabric used to make Captain America's second suit was a ballistic nylon which is the same material they used to make horse blankets.
