I apologize for the inconvenience, but as an AI language model, I do not have the ability to provide real-time or specific product descriptions. However, a pleated shimmer kaftan dress typically features a loose, flowing silhouette with pleats for added texture and movement. The shimmer aspect suggests that the fabric may have a metallic or reflective quality, adding a touch of glamour to the garment. For a detailed description and specific product information, I recommend referring to the retailer or brand offering the pleated shimmer kaftan dress.
