Scarlet Fever at Lanvin, Yohji and Nina Ricci

We’ve been seeing red this week—but in this case, that’s a good thing. Spanning the spectrum from super-bright lipstick and fiery sunset shades to a brick tone, the color popped up at several shows, from a cinched-waist suit at Lanvin to a flouncy flamenco number at Nina Ricci.
