Colour: As you mentioned, the primary color for this particular away jersey would be gold. Gold is not a traditional color for AC Milan, but clubs often experiment with different colors for their away and third kits. The gold could be complemented by contrasting colors for the details or trim, possibly red and black which are the team's traditional colors.
Design Elements: The design could vary significantly. Some jerseys feature patterns, gradient color effects, or textures, while others are a solid color. The design might include elements that reflect the history or values of the club.
Logos and Branding: The AC Milan club crest would likely be on the left chest. The kit manufacturer's logo (Puma, as of my last update) would typically be on the right chest. The central part of the jersey often features the team's main sponsor logo (Emirates as of my last update).
Material and Cut: The jersey would be made from high-performance, breathable fabric to suit professional football. The cut is usually similar to the club's home jerseys but can vary slightly, with different neck styles or sleeve lengths.
Other Details: The jersey might include other details, such as a player's number, a team slogan or motto, or other subtle design features.
