Don’t get anything expensive. Ulta, morphe, ELF, real techniques all have great beginner friendly brush sets. Just make sure there’s a mix of eye and face brushes and at least 6 in the set. Cheaper brushes are fine to use and more expensive ones don’t make that much of a difference in terms of quality. Just make sure the handle has a good counter weight and the bristles won’t fall out. Also this is a personal preference but I’m not a fan of brushes with a wooden handle because I can’t wash them without the wood cracking. I prefer plastic for that reason.
