Don't own any Sigma brushes or don't know where to start? Hopefully I can help you here!
Half of my brush collection is Sigma's. I really love their brushes (tbh so much better than Mac which is also more expensive). They last long, are reliable and good build and quality. (Click to go to the Sigma Website)
Here I'll be recommending the brushes that I think are the basic staples in any makeup lover's beginning collections. I'll also think of the more experienced brush musers and add a few professional brushes and quality kits that I think are amazing and you should definitely be considering trying.
Small (eye, concealer, lip) brushes first, then big (face) brushes. Let's start! ^___^*
