I definitely engage regularly in foundation crises. I feel like in MUFE I am always between shades. I was between shades in F&B, too. With a little self tan I am a perfect 18. To ensure its not streaky, I apply with fingertips then blend with MAC foundation brush. I like the finish, semi glowy but not slick or greasy (like Maybelline Fit Me), more coverage than F&B. Long wearing. But I'm not blown away done they don't have my shade.
