Hard to describe, elegant-one. So sorry. It doesn't feel like a Walgreens gift brush set by any means. It's just more coarse than I expected it to be. I've got softer brushes from Lancome, MAC, MUFE, and NARS. It feels like a Sephora blush brush I had. The low density of the bristles, however, make it less scratchy than it potentially could be. (Stabby was too strong an adjective. I'll reserve that for Dollar Store sets.) My skin is a touch sensitive and I was expecting spun silk. I envisioned drooling and passing out while swirling on my blush. Okay not so melodramatic, but I've been reading reviews on this brush for years it sounded like people were having NARS' most famous 'O' blush. Apparently it takes more than 50 dollars to make me holler.
Not as soft as I expected is honestly the best descriptor I can think of at this time and I know that's terribly subjective. It's extremely lightweight for the reasons MarieMary described. If you hold the handle toward the end when you apply your blush you are making even softer strokes. Like she said, you really can't be heavy handed with it. I think you should try it out. I have often suspected I may have gotten an off brush.
