You could try a lip stain - most of the cosmetics brands that are available in department stores make them. They're usually a liquid/gel that you can dab on, build the colour, and then either leave it as is or pop some shiny gloss over the top for a bit of extra *pow*. The stains are called that for a reason, they do last all day, and as a fellow full-lipped gal, I find they give just the right amount of impact and emphasis on your lovely mouth, without making your lips look like they're collagen enhanced, kwim? I only wear lippie for formal occasions where a big slick of matte red is called for, because I look like a trout... same goes for most coloured glosses, I just stick to Lip Smackers with a bit of a stain underneath (the one I'm using atm iiissss... Maybelline or Covergirl? I think?) and I have a nice little flush of colour but not tooo much Good luck!
