The outfit shown in the image is a men's traditional ethnic set, universally known as a Kurta Pyjama. The ensemble consists of a long tunic (kurta) and loose-fitting trousers (pyjama or pajama).

Kurta Details:
The kurta is a vibrant mustard yellow or arylide yellow color and features an all-over intricate print in a contrasting white or off-white color. This specific type of design is often referred to as a hand block print, ethnic motif print, or jaal patterned design. The kurta has a straight-cut, regular-fit garment that typically extends to the knee. It includes a stylish mandarin collar, also known as a band collar, and full-length sleeves. The fabric is commonly a comfortable and breathable material like pure cotton or a cotton blend, ensuring you stay cool and stylish all day long.

Pyjama Details:
The accompanying bottom wear consists of solid white or cream-colored pyjamas. These are loose-fitting trousers usually made from a light-weight cotton fabric for maximum comfort and ease of movement. They often feature a drawstring or elasticated waistband for an adjustable fit and a plain or straight-style bottom.
