Mark Vanderloo for males, I think it was the shot of him with his hands down a pair of black boxer briefs in black and white, I saw it and started researching who he was.
For females, around the same time I was getting familiar with the fashion world and obviously the most commercial were the VS Angels and obviously Gisele was the huge name, watched the 2006 show and Alessandra Ambrosio just stood out, she was the second one out and the closeups they did on her face just sold it, especially that outfit with the black lingerie, big white wigs with the poker markings on them. Karolina as well, her walk and turns in the first segment then her opening the other two segments with the lower shot going up focusing on her walk, body, bra and face, she looked like a real life barbie.
