My absolute number one tip for spring is to prepare your skin before applying any makeup, because either your spring makeup is bright or natural it will look much better with good skin surface. I think for spring you should use little bit more color, brighter lipstick, colored eye pencil or fresh eyeshadow, even blush. Lets be honest, not everyday is carnival and most of us wear natural makeup, but for spring we definitely need some pop of color! :)
