First i have to make a disclaimer as someone who really knows a lot about astrology that you should look at you ascendant and your moon to get complete picture of your real star style,but if you dont know where your moon and ascendant are (in wich sign) it's totaly ok to base your opinion just on your sun sign,because that is our ego planet,and the sign our sun lays in is what we are showing to the world willingly. (if you would like to find out where the rest of your planets are,you can make your chart here astro.com )
So every sign in zodiac has specific behavioural,emotional patterns also known as characteristics,and those characteristics can and will be reflected on fashion of those signs,belive me,they will be reflected on every aspect of ones life,but fashion is their first victim,because our personal style is one of our first ways of telling to the world around us who we are,what do we value,what our emotional and mental state is. So let's just find out what each sign is most comfortable in,and in what kind of clothes the chances are we will often find them in!
