In my opinion, the style of clothing is very important, especially when we are living.  It defines you as a person, makes you stand out, get out of anonymity, show others what kind of person you are.  His own style of choice chooses each person and depends on his temper, his character, the music he's listening to or the season he's in. 
Obviously, the vestibule style also depends on where you are or the event you attend.  Some events require a stylish dress code, even if it does not fit your style.  People looking at you and the clothes you wear, the way you are dressed, can figure out what kind of man you are, what character you have, what you like to do, I can get to know you without interacting with you. 
Some people do not emphasize the way they dress, but personally I am passionate about this area and I like to dress properly for my style and place where I go. 
In conclusion, fashion style is very important for every person because it can be like a business card.
