[POLL] Let’s Take It Back…..Way Back

I’m talking about taking it back to almost 3 years ago. Earlier, I stumbled upon this collage,

showing pictures of the girls’ past concepts from their “Into The New World”/”Beginning” days til the most recent, “Run Devil Run.” It also allows us to compare their different concepts, which is why after seeing the collage,  I just had to make a post and poll about it for fun.

Pictures’ Sources: As tagged + Soompi

Among all their concepts since their debut up this point, (Into The New World, Girls’ Generation, Kissing You, Baby Baby, Gee, Genie/Tell Me Your Wish, Oh, and Run Devil Run), which is your favorite?

& tell us why your choice is your favorite below :]
