Fun fact: Street Fighter 5's new Capcom Pro Tour-themed costumes are a callback to classic artwork
While some might believe that these alternate outfits are new designs from the company, that actually isn't the case. The inspiration for the costumes comes from an old piece of promotional artwork that appears to be from sometime during the Street Fighter 2 era.
Cobelcog on Twitter recently pointed out the similarities and believes that the artist is Kinu Nishimura, one of Capcom's main designers / artists. I couldn't find much on the art piece or where it originated from, but based on Nishimura's style, I'm inclined to agree with that assessment.
Last year's CPT costumes for Chun-Li and Cammy were also derived from this artwork, and you can see all four outfits along with the promotional piece below.
