Functional: This outfit seen worn by Kate Middleton is "useful" because of it's functionality. Kate took a very casual ensable and dressed it up. She's comfortable but would look appropriate if she were to run into anyone. She wore flats instead of heels for comfort and added a silk scarf to dress up the look. The outfit is "beautiful" because she incorporated the bright colors. Both the jeans and splash of color in the scarf enhance the look. The blazer is tailored to her perfectly as well.
