South Korean girl group RAINBOW revealed the jacket picture for their second Japanese single, "Mach".

In the picture, we can see the seven girls sparkling like never before, wearing a shiny and sexy combo of short golden jackets and tight silver pants.

The group made their debut in Japan with the single "A" and garnered quite some attention with their infamous 'ab dance'. For the new song, "Mach", the girls are going to continue to expose their midriff.

Leader Jaekyung commented about the outfit, "Don't we look cool and stylish! Please keep an eye on our sparkling selves."
