At $65 a pop, is it worth it?

I’ll admit it: I’m a mascara junkie.  I buy a new tube about every month, and am guilty of applying it more than once a day.  I’m also a cheater.  I never stay loyal to a brand for more than a few months at a time.  I’ve found that there’s always something newer, darker, and sexier to try out.  Lately, I’ve been obsessed with Laura Mercier’s Thickening Mascara, and love to layer it on for that ultimate wide-eyed effect.  But I got that itch today and decided it was time to move on.  While checking out the latest fall beauty at Nordstrom, I was absolutely amazed to come across Sisley’s Phyto-Mascara.  Sure, the brush looks lush and the tube is pretty standard — but the price!  At $65 a pop I’ve got to know — is it worth it?
