Raquel, to me, defines the anonymous-yet-omnipresent-top-model era. lol. all these girls working non-stop, landing campaign after campaign and editorial after editorial and yet so entirely unknown by the general public. Raquel sorta represents the epitome of that. she has zero fame outside of the fashion world (perhaps it's a different story in Brazil, i'm not sure), yet she has one of the most elite portfolios of any model in the past 10 years.
who were the other number ones? Gisele -- introduced the Brazilian Invasion. and like Charlotte said, "return of the sexy model" (inspired folks to book Ale, Adriana, Fernanda, etc) who was after her? i think KK from 2002-2004. she led the way for the eastern european girls that flooded the catwalks and scored the campaigns in the years following (think Natalia, Hana, Eugenia, Natasha, Snejana, etc). then Gemma - ushered in the total baby doll look. Daria was the bohemian chic supermodel. very casual and laid-back. i don't know if she was particularly influential in signalling any new trends in models or fashion, but she was unarguably deserving of the number 1 spot. then Raquel and next was Lara. she brought boobs back. and, as was mentioned, the gap-toothed trend.
Anja is having a great year, a great 2 years even. but she doesn't deserve the number 1 spot, imo. i'd give it to Freja first - and i'm not even a fan. it's not just about her being an individual and being uniquely androgynous. she's just got the sort of exclusivity at the moment. i still don't think she's ready to take the place of Lara, though.
