This is the diagram I use.
Now for the contouring, take a foundation 2 shades darker than the skin tone. Apply this right under the cheekbones, bring it to the temples of the face (The lower parts of the forehead) And underneath the face, This will give shadow making your face look thinner. Also apply the darker foundation (I recommend a small thin foundation or eye brush for this) and apply in two lines to the end of the nose. (This will make it look thinner) also I like to do a 'V' shape at the end of the nose. If you are finding it hard to keep up, look at the diagram. Now get a cream foundation brush and blend it al together, but keeping the contour you just did. By this time, I like moving to a buffing brush, to blend it more. Remember to buff some do the neck to even the skin tone.
Next Powder the face. Use a transparent one so It doesn't throw more colour onto the face. You can exaggerate the contouring with a powder contour or highlighter, but I like to skip this step.
And your done. You can obviously finish the makeup with a beautiful eye look, or a bright red lipstick. I think this contouring looks especially elegant on brides.
