Makeup advice needed

OK so i have a confession to make, all you lovelies out there all talk about these amazing foundations by Mac or Chanel or Dior, but i only own ONE foundation and its from Avon
And i barely use it
Maybe once or twice a month if i go out somewhere special (i hear gasps from the makeup community)

I really want to purchase some nice makeup but i don't wanna spend a lot of money just for spending sake.
If there is a cheap great brand- I'm sold (which is why i use Avon- some of their stuff is amazing)
Now don't get me wrong, I'm not against spending for quality but i just have never felt i wanted to buy these things. I do own some medium priced make up such as Urban Decay and Barry M. Plus i love my 8 Hour night cream- which isn't cheap.

I would really love it if you all could suggest some fab make up for me to try.
Your must have items!

You can all see my colouring by my pictures.
I'm really pale, with blue eyes and (coloured) blonde hair. It's naturally mousey brown and i have a few freckles. I also have combination skin.
Which at the moment is breaking out on my chin (grr)

So please feel free to comment
I really need the advice
Much love to you all
