Colour-blocked shades of white, blue and red lend Valentino's blue wool and silk-blend mini dress a distinctly preppy verve. It's tailored in Italy with a slim-fitting bodice – note the angular darts above the waist – and long sleeves that are trimmed with red piping and an exaggerated white ruffle, then finished with an inverted pleat down the front of the cropped skirt. Save it for a special occasion, styled with leather loafers and a cross-body bag in a bright yellow hue.
