When I think about great, inexpensive makeup brushes, the Real Techniques are the first that comes in mind! Their bristles are really soft for drugstore brushes and are very easy to wash/dry since they're synthetic and doesn't loose hairs. These brushes designed and created by the Youtube channel Pixiwoos. My favorites are the Expert face brush (for foundation), the Stippling brush (for foundation) and the Contour brush (for blush or contour).
You can but them here!
