Ond of the basis to look sharp at all times is to find your own style and stay classy. If, like me,you like colors, wearing fancy black and white or blue and beige suits and co-ordinates is not going to satisfy you. However,obviously, you might not get the choice but if you just have to look like you are paying attention to what you are wearing. There is also make up. The best way to look professional is a good manucure. When you work in an office, you will probably be writing a lot or typing on a keyborad for the most part of your day. If you are sure of yourself, you can go for the bold red lip and black liner. If, on the other hand, the red lip is not appliable every half hour and that you are not the best at liner, or just that it would take you far too much time in the morning to apply it: go for nude. A nice nude shade on the lid, a little darker in the crease and mascara for the eyes. For the lips, a rosy toned lipstick or a dusky mat pink shade. For the face, CC than BB creams and you are good to go. When you wnat it to stay really put for the day, powder up with a universal or translucend powder.
