@bzjash How much are you using? The first mistake people make with them is applying too much. Take a pin sized amount on the brush and that is usually enough to cover both lips. I also use a lip primer sometimes, and to prevent bleeding a clear lip pencil(or a pencil in a shade of the lip color if you want) helps. I've never really needed a lip pencil but I know a lot of people have issues with them bleeding so that can help a lot. But number one, make sure you use a tiny amount to start off. Hope that helps. :-) 

@Whimsical Kelly If you don't mind my asking, how does Black Dahlia compare to Strumpet?  I've been on the hunt for a replacement for my favorite, now-discontinued red lippie.  It was a deep, saturated cool red, pulls slightly berryish if applied lightly.  I've found a few close-but-not-quite, most of them are a shade too purple or too bright.  I'd thought from seeing some swatches that Black Dahlia might be a fair dupe, but Strumpet sounds similar in this post, so I'm wondering how they compare.
