Material: The set appears to be made from a lightweight, flowing fabric, likely crape as you mentioned. This material is known for its graceful drape and comfortable feel.

Color: The dominant color is a vibrant shade of royal or cobalt blue.

Design and Pattern: The entire set—kurti, pants, and dupatta—features a traditional Indian print. This pattern resembles "Bandhani" or "Bandhej," which is a tie-dye textile decorated by plucking the cloth with the fingernails into many tiny bindings that form a figurative design. The intricate white dot-like patterns form various geometric and floral motifs across the fabric.

Kurti:

 * Neckline: V-neckline with a band of intricate gold-colored embroidery or embellishment, adding a touch of elegance.

 * Sleeves: Three-quarter length sleeves with a matching print.

 * Fit: The kurti has a straight, comfortable fit, extending to approximately knee length.

Pants:

 * Style: The pants are a solid blue color, matching the base color of the kurti. They appear to be straight-cut or cigarette-style pants.

Dupatta:

 * The dupatta is also made of crape material and features the same Bandhani-style print as the kurti.

 * It has a wide white printed border, which complements the overall design.

 * The length is generous, allowing for a variety of draping styles.

Overall Style: This is a classic and comfortable ethnic wear set suitable for various casual, semi-formal, or festive occasions. The combination of the vibrant blue color, traditional print, and a hint of embroidery on the neckline makes it a versatile and stylish outfit.
