Instead of brands, I think its depend on what look you are trying to go with and your price range. You can use drugstore brands such as L'oreal, Maybelline, NYX, NYC, Revlon, Physicians Formula, Almay, Covergirl, etc.
You say you need simple makeup. Are you talking about a simple makeup look? If so, I would say either foundation/tinted moisturizer/bb cream/powder with eyeliner (and maybe eyeshadow if you like), clean eyebrow, and a lipgloss/liptint. Blushes and bronzers and highlights are necessary. Remember you wanna try to look natural but nice put together also.
