"I Am The Best" was used for a short video featuring talented young dancers Larsen Thompson and Taylor Hatala showcasing powerful moves choreographed by Janelle Ginestra. "I'm the Best" plays in the background for a short 40-something seconds, to which the dancers execute swift, almost knife-like sharp choreography. The costumes the girls are wearing during the part of 2NE1's song (starting at 1:30 in video above) seems to be distinctly 'Asian' but not 'Korean' including buns decorated with chopsticks, a Hanfu-inspired crop top, and simple black skirt and sandals. The makeup also derives some inspiration from the traditional Japanese style of cosmetics.
I thought the video was seriously cute! :-)
