The outfit in the image is a men's traditional ethnic set 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 deep olive green or dark brown base color and features an all-over intricate print. The design is a traditional textile pattern, widely identified as a paisley print or tribal print, using multiple contrasting colors such as red, orange, and beige. The kurta is 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, making it suitable for all-day wear.

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.
