No matter how you look at it, picking an outfit for a wedding can be a challenge. And when it's a fall wedding, especially, the dress code gets trickier. While vibrant florals are for spring, bright colors are for summer, and lush velvets are for winter, what the heck is for autumn? The key to nailing the perfect look is opting for something celebratory but also seasonal. Think: punchy autumnal colors, rich textures, and even inky fall florals.
