My foundation always look clumpy and orange?

I often have the same problem. Because your skin is so pale you need to apply it really lightly. Don't cake it on whatever you do. The reason it looks streaky and orange is probably because with an applicator like the one on the foundation you're using you're more likely to use too much, and not spread it properly. If you insist on using liquid foundation, try using disposable foundation sponge, and make sure you're blending properly! However, for you're skin tone, you're better off going a little more natural and using a powder foundation. To avoid that dry, powdery look you often get with powder foundations, apply moisturiser before AND after applying the foundation. If you're worried about pimples or looking to shiny try an oil free moisturiser. A good one is Clean and Clear Oil Free Skin Balancing Moisturiser.
