I was a tad skeptical about this lasting 16 hours. Like, why even would anyone need lipstick to last so long? Well, I'll tell you why you would need this. Usually, when I party on a school night, my next routine is changing into work wear, and hope my make up looks presentable for office life. After a long night of marathon drinking and occasional binge eating , I never anticipate my lip color staying. It's usually the first thing to go. Well, the other night I went up clubbing, the next morning the lip color was still on and looked great! I even brushed my teeth, and it was still there! I know my partying life maybe looked frowned upon, but I make it a point to get to work at a decent time everyday (I got to support the habit somehow). But yes, I love this stuff for giving me confidence knowing that even I'm a hot mess, my lips look good. Thanks Rimmel.
