They advised us to bring 2 casual photos. One needs to be full length and the other can be waist up.
Full length (women)- they told us to wear a tight-fitted shirt. Don't wear a long or over-sized shirt. Wear jeans or leggings. They told us no dress or skirt. Heels. Not too much jewelry. Basically, a picture that shows off your figure in a natural setting, where you look nice. You can have your hair down. Make-up on point. Red lipstick not necessary but it IS the Emirates
Same rule for half length photo.
No idea what the requirements for male candidates because I wasn't really paying attention since it didn't apply to me
Good luck!
