A good fashion show is about more than clothing - a model can make or break just how badly you want to wear what's sent down the runway.For the fourth day of Sao Paulo Fashion Week, that idea seemed to ring true; although Gisele made an appearance on the runway earlier this week, today's shows were overrun with some of the most photographed faces of the moment. First up was Brazilian model (and owner of some of the coolest shoes I've seen all week) Daiane Conterato. Although she's walked more than her fair shares of shows, today had her closing Reinaldo Lourenco. The clothing may have hinted at works by Gareth Pugh and Balenciaga, but the structured shapes, armored bodices, and oversized shoulders were a bit more wearable (even for the non-Sasha Fierces out there).Bruna Tenorio has also been a runway marathoner this week, but looked her best today, at the Animale show. Maybe it' s her long neck or big, almond-shaped eyes, but she glowed in the Brazilian label's feminine, floaty designs.But the big news of the day was that not one but two of the fashion world's reigning superstars would make an appearance. First up was Agyness Deyn, who made her Sao Paulo Fashion Week debut at the Ellus show. Although there were grumblings beforehand that she wasn't giving a press conference, the complaining stopped the moment she stepped onto the runway. It seems that no one makes baggy jeans look quite as good as Agy. The rest of Ellus' collection - mostly workwear-turned-nightwear - featured a few interesting denim treatments and very on-trend jumpsuits.Closing out the night was Raquel Zimmermann, currently ranked as the number one model in the world. You'd never guess it backstage, where Zimmermann munched on burgers and chatted with reporters. She also has quite the good humor, seeing as the pieces she wore down the Animale runway were some of the weakest of the show. But it makes sense: Give Zimmermann the duds of the bunch and leave the sculpted chiffon dresses that will look gorgeous anyway for less-able models, since the Brazilian can make just about anything look good.
