Your makeup routine will determine what brushes you need to bring into your collection. Some women don't do much eye makeup so they can skip some of the detail-work brushes, for example. But one brush every woman should invest in is a great blush brush. Your blush brush is a multi-tasker for your makeup kit. Get a brush with natural fibers for best results. Start with a great blush and keep expanding your brush collection. You'll have a great set of professional make up brushes in your bag in no time!
