Watch What I'm Wearing/Mixing Patterns

This was my first attempt at mixing patterns and I'm still not sure how I feel about it.  I kept it simple by only using three colors, black white and red.  I also feel like stripes are almost as simple as it gets as far as patterns go.  But I never do this and so it felt a little weird.  What do you think?  Will you wear two different patterns at the same time?
