I know that you don't use the same type of makeup everyday but for school I have a style I normally use, because my school has a strict school uniform.
(eugh, my nose looks massive in this picture) This is my school makeup. I wear a lipgloss that matches my natural lip color, a light blush and a foundation one shade lower than my natural color skin to make myself slightly paler. I used some khaki eyeliner to firstly line my eyes then to flick it up/down continuing it's natural path along my eyes. Then I put some mascara on my upper eyelashes and used my mums eyebrow pencil (or whatever it's called) to darken my eyebrows.
