The cliche about Brazilian bikinis is that they're tiny (hence the abbreviated personal topiary of the same name) and louder than Rio during carnival. But the chicest Brazilian girls aren't wearing hot-pink micro-suits. Instead, the trend is for larger bottoms and subtle colors, like these downright sedate styles from Jo de Mer (a favorite of Gisele Bündchen, a woman who knows her bikinis), Beach Couture (whose collection for Topshop arrives in stores this week), and Adriana Degreas (known for her luxe aesthetic). Basic, it seems, is the new bling.
