After the shutdown of GameSpy in June 2014, the outfit was no longer obtainable through the Social Club website. However, a free game update released on the same month unlocked the outfit (and other Social Club rewards) for everyone.
Once earning the suit, players also unlocked the Gentleman's Attire and Lady's Finery that can be used for customizing their avatar on Xbox Live and PlayStation Home. This was added as a reward for completion of a 2011 multiplayer XP contest.
This is the only other outfit besides the Cowboy Outfit that is present at the beginning of the game. (However, the player cannot put it on until completion of the mission New Friends, Old Problems, as the safehouse is not functional until then)
When worn while playing as Jack Marston, his hair will be tied in a short ponytail in the back. This isn't present with any of the other hatless outfits.
The 'High Stakes' Poker game costs $250 to enter, and cheating is not an option, as the player cannot wear the Elegant Suit while playing here. Using this outfit in the high stakes poker games can be an easy way to get the High Roller trophy/achievement.
This outfit is shown in one of the trailers when the narrator says: "You may get a great deal wealthier in the process."
Note that when wearing this outfit, the player may receive different dialog from NPCs e.g.: Cowboy Outfit- "Who's this cowboy beside you?" Gentleman's Attire- "Who's this nice man beside you?"
This is one of the five outfits that doesn't have a hat. However, in certain missions (like The Burning) he will be wearing a hat.
Humorously, Marston will still greet people by tipping his hat at them, even though this outfit has no hat.
Marston's Bandolier is not shown while wearing this outfit.
This appears to be the only outfit that doesn't get dusty.
Sometimes when changing from the Gentleman's Attire to the Elegant Suit, the player will still look like they are wearing the Gentleman's Attire, but have the effects of the Elegant Suit.
John's hair becomes longer while wearing this outfit, while Jack ties his hair even though his isn't quite as long.
This is the only outfit that changes Marston's facial hair.
The Gentleman's Attire changes the color of Marston's gun belt and holster. The only other outfit to do that is the US Army Uniform.
When using the sharp dressed man cheat, Gentleman's Attire will be given to the player. However, since the game disables saves when cheats are active, this outfit will be locked again when the player exit the game or loads a previous save.
