Both terms are used to describe the way you dress. In the same way, the difference between style and fashion can be attributed to different reasons. A fashionable outfit may be a reflection of your personal style or a reflection of the world around you. However, a fashionable garment is the key to a stylish life. If you're a fashionista, you'll always have a personal sense of style. The more you're aware of what your preferences are, the better suited outfit you can choose.
