Wearing black high-heeled boots and shorty unitard the girls literally grab "Attention" with their precision choreography. The fact that it's just the practice room is totally lost on them, as they perform as if there was a huge crowd watching.  

Recall that "Attention" is WANNA.B's declaration to the world that they are "stars" ready to succeed. Time will only tell just how far the group will get, but they are certainly off to a great start.

Were you impressed with their choreography, or was it disappointing?
