Alternate costumes were technically introduced in the Street Fighter Alpha series with Chun-Li. In her appearances in the series, she wears a set of athletic gear from her younger days. In Street Fighter Alpha 2 (and X-Men vs. Street Fighter), players can choose between this costume and her Street Fighter II clothing. In Alpha 2, the input for her Kikoken will differ depending on the costume (her "normal" costume uses a half circle motion, and her "classic" outfit uses a charge motion). This technically makes Chun-Li the only character with a costume that affects gameplay.
