I own only a couple of brushes...one big one that I use to apply blush (initially received it for free in my mineral makeup starter kit) and two smaller brushes that I use for eyeshadow (I think they were $1 each at Target). (This is partly because I keep my makeup in a little makeup bag and frequently tote it to work to apply later in the morning after I've had 3 or 4 cups of coffee and can function, so not much room in the little bag for brushes.)
But I'd like to get more serious about makeup application, and it seems this involves using more brushes. I was at sephora over the weekend and randomly picked up a big brush, and it was soooo soft, I had trouble putting it down. It was about $50. For one brush. I almost bought it, even though I had no idea what it's supposed to be used for, just because it was sooooo soft. But I didn't...because it would be silly to spend $50 for something I might not need and don't know how to use.
So I guess my question is this - are makeup brushes one of those products where you get what you pay for, and it would make sense to spend a bunch of money on a fancy brush...or can I get away with buying something a fraction of the price? Also, if you had to choose 3 or 4 brushes only for all your makeup needs, what would you consider to be the most indispensable brushes in your collection?
