There is white lace or trim along the neckline (V-neck) and on the sleeves.
The sleeves are about three-quarter length or just past elbow.
Cut is straight, long kurti, with side slits (common in kurtis) so ease of movement.
The material looks lightweight, possibly a blend: maybe cotton or cotton + a silk blend / synthetic that gives a slight sheen.
