I am saying this because logo has invariably been given a huge importance in clothing businesses and if you have just tipped your toes in the apparel business then you should get it as soon as possible. Even blue chip companies have logos that are considered as the state of the art brand identities in the world.
It is a cash cow for big brands like Armani and Prada; this is why it is on the top. What do you think, what is the secret of these big brand identities? So, let me tell you that there is nothing out of the world in them. As far as I think, they believe in creating a simple brand identity which is not commonly observed today. What I want to say is people are after creating funky, upbeat and over-done Clothing Logos which sometimes doesn't go with the theme of the clothing business.
Colors are the most important aspect of corporate identities which can be used to enhance or destroy the quality of it. Colors that are mostly preferred in apparel identities are normally black and pink. Pink is usually used to depict a women's fashion brand. Color scheme is decided on the basis of the nature of business you have. For example; a wedding dress boutique's identity would be totally different from a garments company's identity.
Just like the color mechanism involved in these corporate identities, there are some symbols and objects as well that are usually considered important for such brands, for instance; you may find a stylish women or a dress incorporated in Clothing Logos which are counted as the best identifiers for an apparel business.
Some of the small apparel business owners try to do it on their own which gives them undesired results. Obviously, an amateur won't be able to design a perfect piece of art as he is not a professional. No wonder, he has loads of innovative ideas in his mind but chances are that he won't be able to encapsulate those ideas in his brand mark identity.
