Content is the main component of success in the fashion blogging. Remember, first at least for half a year you will work on the content then it will work for you.
It means that at the beginning you need to find the photographer who will make photos with a good quality for you. Also you need to take care of where you will take clothes. It should be fashionable and stylish (and it doesn't mean expensive clothes at all).
The simple photo where's your face in a usual polo-neck won't make you the fashion blogger.
Watch the quality of photos and regularity of post creation. Photos have to be professional and qualitative, show your taste.
Fifth — your personality is a key thing
Show the best sides of you. At the same time remain sincere, don't try to draw attention only with outer special effects. Your unique point of view — a true source of inspiration and an example for your followers.
If you love bright colors, show dresses in bright colors and be not afraid of criticism.
Give the honest opinion on clothes, trends, advertising products — your readers will appreciate it more than just the beautiful pictures.
