To really spice up an outfit, don a fun, colorful hat. Hats are a great way to add personality to your outfit --- and cover up a bad hair day. It is important to tailor your hat to fit the occasion.
For example, you do not want to wear your favorite worn-in college baseball cap to the office. Purchase hats with your existing wardrobe in mind. Each hat should have an outfit; otherwise, you will never wear it.
Baseball caps should be reserved for days spend running errands or going to the park. Fedoras and newsboy caps are great for nights on the town. Small, colorful straw hats are good the office (though they might not last the entire day because of the comfort factor).
Wide-brim, natural straw hats are great for just about any occasion. Do not always try to hide your hair under a hat; sometimes, it is a good idea to style around your hat in case you have to remove it.
