I noticed this a while ago but I decded to post it now since I just purchased this shirt from Forever21 and Kim Kardashian, Jessica Biel, and Megan Fox wore a similar shirt to this.
Here is Kim Kardashian wearing it. This picture was taken from Singer22.com
Megan Fox in the same Zipper tee.
Also Jessica Biel...
They all wore this.

UPDATE: As of 10-10-09 This Shirt was made available. Which looks like an exact replica of Kim Kardashian's and Megan Fox's Tee.
