Um, can they get any cuter and hotter at the same time?

Every girl's crush, MAMAMOO, dropped yet another teaser image ahead of their release of full-length album, 'Melting Time.'  So far, it seems the third preview track they're teasing for may be called "1 CM," but we can't be sure yet.  It'll be out on February 11.

In this teaser image, the girls look like they're in jail, wearing cute orange uniforms that not everyone can pull off.  What might their concept be then?
