Here it goes again.

After Prince William and Kate Middleton's official engagement portraits were released on Saturday, a frenzy over the chic outfits Middleton wore has begun.

However, whereas the blue Issa dress the bride-to-be wore sold out in hours and prompted cheaper look-alikes, the two white ensembles from the engagement portraits shot by Mario Testino will be making their way back to retail stores in 2011.

Instead of opting for a designer look, Middleton shopped her closet and settled on a cream, silk blouse from the high-end store Whistles for the casual look, according to the Telegraph.

Because the blouse is from the store's 2008 fall/winter line, the blouse cannot be bought in stores…for now.

"We are delighted that Katherine has chosen to wear Whistles in her engagement photographs," CEO of Whistles Jane Shepherdson said. "Due to a surge of customer interest we will be re-releasing the 'Kate' blouse as a limited edition in early 2011."

For the formal shot, the 28-year-old bride-to-be wore a white Reiss Nannette dress. "Kate has been a customer of Reiss for some time now and we are absolutely delighted that she chose to wear one of our dresses for such a wonderful occasion."

A similar version will hit stores at the end of January 2011.
