Street Fighter 6 fans are divided with their response to the roster's unlockable Outfit 2, particularly with Cammy getting her classic sexy green swimsuit look. Some fans dislike the fan service, while others are happy to see its return.

Street Fighter 6 is being hailed as a return-to-form for Capcom's iconic fighting game franchise, compared to 2016's divisive Street Fighter 5. Response has been largely positive to SF6 and many fans are already calling it the best fighting game on the Steam platform. It has already reached over 1 million players (compared to SFV having less than half of that number during its first week after launch).

Just a day prior to the worldwide release of Street Fighter 6 last June 2, Capcom announced all the World Warriors revealed in the current roster will have a second outfit that can be unlocked.

According to Capcom:

Fans of the classics, rejoice! Behold Outfit 2 for all 18 characters featuring looks for returning fighters from previous games in the Street Fighter series. New characters have their personalities on full display in their own drip. Unlock Outfit 2 for each character during your adventures in World Tour. Alternatively, Outfit 2 also can be purchased instantly with Fighter Coins.
