When elegance and sex appeal are serious business, go straight to Lilli Diamond, high-end Los Angeles dressmaker who dished dresses to all the fifties’ film star greats. This number is a scintillating, silk-lined, chrome spun lurex, a mid-century fabric with the body-conscious drape of crepe rayon. Inky indigo is shot with silver, creating a sharkskin effect that sparkles, or mattes to black, with every twitch. The bust effect is what you expect of a bombshell — carefully-draped to create a high-cut, unfussy, sweetheart-at-the-keyhole knockout. Wiggle silhouette highlights the body. Can’t say enough.
