Such a large scarf could overwhelm a petite woman like Justice Ginsburg, but this pattern echoes the angles in her facial features and works to soften her look a bit. Without the soft folds of the scarf, her large glasses and smooth hairstyle might look severe.
Justice Sotomayor wore a black suit with asymmetrical buttons and lots of jewelry:
The suit is pretty conservative, and Justice Sotomayor would have benefitted from some color near her face. But have a look at her jewelry! Dangling earrings and lots of stacked silver bracelets. This is not the pearls-and-button-earrings jewelry set that was standard issue for the previous generation. This jewelry reflects her personal style and makes what would otherwise be a very plain outfit considerably funkier.
