(Acceptable) The best option would be gray shirt. Casual clothing in solid colours is fine for a passport or PR photo. Scoop necks or v-necks usually work well. Just be mindful of low necklines or tank tops—if the neckline is too low, it may appear as though you’re not wearing anything in the photo. (Unacceptable) Since you will be in front of a white background, avoid white shirt. Government officials often reject hooded sweatshirts and not accept sunglasses and tinted eyewear in passport/PR photos. You may wear clear eyeglasses, but there can be no glare in the photo. For that reason, it is usually a good idea to remove your glasses. Hats or other head coverings are not acceptable unless they are worn for religious reasons. Uniforms or anything that resembles a uniform (including camouflage) are not allowed. Wear a minimal amount of jewelry. ---------------
