You can blur the line by just one piece of accessories like a pair of good quality sunglasses, a leather jacket or a shirt tied around your waist. However, whatever piece you choose, it should have a sleek and sporty feel itself, otherwise it might do more harm than good.
If you do not feel certain as to how to try the trend on yourself, just start with pieces that seem safe for the moment. For example, you can stick to colors like black, white or grey, which are all-time classics, and later on you can experiment with other brighter colors and prints provided you
feel comfortable with it.
