If you’re looking for an amazing alternative to the It Cosmetics Heavenly Luxe Complexion Perfection Brush, I’ve found it. They are nearly identical. How do I know? I went to the store to check it out. It’s so coveted Ulta has it CHAINED to the display. 
The one from IT is $49. The save version has a great price and a digital Q on Amazon. You get your foundation AND concealer brush in ONE! Dense, soft, no shedding! I HIGHLY recommend it! See the splurge version here.
