This is a classic Lauren Ralph Lauren black wool crest blazer. Size 4. It is a two-button, single-breasted style. The distinctive embroidered crest on the left chest, which is embellished not simply embroidered, ups the sophistication (sometimes just what a pair of jeans needs). A polished and fitted appearance--the structured silhouette is so RL. It is a wool and cashmere blend. Wool alone does not offer the warmth , softness, and texture that a touch of cashmere does. In excellent condition. Wool and Cashmere PTP: 18", laying flat Waist: 16", laying flat Sleeve 26", measured from mid-shoulder
