Blair’s Fashion on Gossip Girl. How cute is Blair’s style on Gossip Girl. I’m like obsessed with this show and Blair’s style. Her style is like a mixture of vintage and modern trends. I adore the flowered headbands, colored, headbands, bows, and hair accessories that she wears each weak. While Serena has a nice style Blair is really the fashionista on the show with her exotic pieces that she wears with her uniform and in her party outfits. Here’s my favorite Blair looks.
