While it’s unclear whether Gisele Bundchen did any trick-or-treating on Halloween, she did get all dressed up. Tom Brady’s better half took to the catwalk in Brazil Oct. 31, part of Sao Paulo Fashion Week Fall/Winter 2014. Gi wore a couple of stylish looks at the Colcci runway show, including a chic black and white mini dress with a plunging neckline and a sporty crop top and shorts combo. Also making the fashion scene in Brazil on Halloween? Victoria’s Secret model Erin Heatherton. But the holiday wasn’t all work for Gi. Last week, the supermodel and her Pats QB hubby donned “Wizard of Oz” costumes for the team’s Halloween bash and playfully smooched on Instagram.
