Last time we were in San Francisco we stopped at the Sephora store near Union Square and I picked up these make-up brushes. Yes, they are indeed an investment, but they'll last forever, and they make the hugest difference in terms of whether your make-up looks professional or ridiculously amateur. I'm not even going to tell you how long it had been since I replaced my old brushes, your opinion of me would certainly plummet to a new low, so let's just say that I'm no longer worried that I'm going to open my cosmetic drawer and have a mutant spore jump out and suck my face off.
