I like the Real Techniques brushes or the Eco tools ones - you can get both in Boots.
Depends on your age as to what make up and als how you r skin is.
If you are on a budget then spend more on foundation. I don't mean the ones that cost £££. Although one of my foundations is from Primark. Bobbi Brown is good for foundation, so is Max Factor, Boots no 7, Maybelline, Rimmel, Revlon do a long stay foundation which is quite covering.
Do you need foundation or would you do better with a BB (beauty Balm) or CC Covering cream which subtly covers. Or even a tinted moisturiser,
Revolution do good eye shadow pallettes, so does MUA.
Personally as you should not use mascara for too long I would suggest trying a cheapie - Maybelline, Essence from WIlco, Primark, Barry M, Rimmel , Boots no 7etc. I also love Revlon.
Eyeliner? Max Factor, NYX, Maybelline, L o'real or boots no 7.
If money not a problem then Bobbie Brown all the way for anything or Benefit. Their blushers are great, I have a cheek palette from them.The Benefit mascaras are top selling. The only reason I do not wear them is I prefer waterproof.
Hope that helps!
