Fall colors are usually of the muted variety, like rich taupe, earthy brown, olive green and plush burgundy. But that didn’t stop stars from embracing a much more vibrant palette this week on the red carpet, running the spectrum from brilliant blues to eye-opening oranges. Other warm-weather elements were also well-represented, including crop tops, cut-outs and florals. Meanwhile, lace, elaborate embroidery and other delicate details collaborated to amp up several looks. When it came to accessories, strappy sandals and structured clutches were favored in complementary hues.
