Primer is great, I've discovered Benefit That Gal which just sort of smoothes things out and gives a hint of colour/brightness but without looking "made up". I often use it on its own without foundation, to just look a bit better without too much effort (I'm really not big on heavy makeup!), but for special occasions when I DO wear foundation, it seems to help it go on better and not look so mask-like. Like "real me but improved"!
For spots that don't want to come out, I use Witch Doctor stick! It's good for irritation too, though if you have broken skin it stings a bit (but then helps it heal). They used to do a gel that was even better, but think it's discontinued now.
Lipstick - I can't wear it either without looking strange, I have an odd lipline at the sides so wherever I put it, it either looks as though I've gone over the edges or missed a bit. My solution was to just invest in fab lip glosses instead and tbh I think they look better on me anyway!
Now my questions:
Why can't I wear eyeliner? EVERY time I've tried it just looks crap, am I just not made for that as well?
Also, I seem to have ended up with a number of tops/jumpers that need something underneath (meshy jumpers, or things with sheer/mesh panels), but I can never find anything to wear under them that doesn't look crap -wrong necklines or whatever. How do you do the layering thing? I'm sick of buying things that look great in the shop, but which I can't then actually wear for real!
