Is This Sonia Rykiel Sweater Really IB Diffusion In Disguise?

I know she like gave birth to the entire concept of knitwears -- seriously, like the idea of clicking two needles back and forth simply didn't exist before she came along -- but I can't deal with this totally '80s Sonia Rykiel throwback sweater:

Clearly IB Diffusion was ripping off Sonia Rykiel back in the day, but this looks like IB Diffusion to me! I'm so confused! It's like I'm walkin' on sunshine!

Anyway, check out this weeeeird YouTube tribute to vintage Sonia Rykiel pieces. What's with the creepy Halloween organ music???


Anyway... YAY OBAMA!
