also as for hair, don't go to crazy or else it looks for a wig, and your natural hair color will accentuate your face the best, and unnatural colors cause people to focus attention towards you and if you want to pass you don't want to get excessive attention
as for makeup at first just use natural colors, they seem dull and boring but will help you to start a base to you makeup techniques and the trick on makeup is not to create your face but accentuate it with makeup
