The best thing about fashion is definitely the ability to mix and match and try out different styles. One day, you can express the most glamour and femininity; the next day, you can go sporty and athletic. For every day, and every mood, there will be your 'comfort zone', in which you feel your best. The picture below depicts one of my favorite (I would say the top three) styles of all: high heels, tight pants, a cool t-shirt and a jean jacket - casual chic with a little gothic/rocker touch. A cup of hot Starbucks and a bag full of make-up I just bought absolutely completes the look.
