This particular photo[ <http://www.soopermodels.com/images/Photographers/antonio/swimwear/SM1042-001-15.jpg> ] is from the same set used by Itzik Gur to make the wallpaper image shown at the beginning of this thread. The shoot was done by Antonio Gallippi for Soopermodels.com. It was used at some point by Stare magazine, with permision I am sure, although I have not found evidence of this anywhere except that Shana Prevette was a Staremagazine model for some period of time. She was Miss Hawaiin Tropic for 2005, as well.
I have gone through the model listings on staremodels.com and looked at a shot of every model from every shoot they did for Stare or at least all they have on the site. I have found only one with ANY model in that particular bikini. Shana Prevette <http://www.staremagazine.com/Image.asp?preview=1878&f=1> So, due to the image from the same set above and the listing from Stare magazine I do believe Ms Prevette to be the model you were searching for.
