If you decided to become a model, you probably already have an interest in fashion, clothes, or photography. You have clothes from specific brands in your wardrobe and know your style well. Still, it needs improvement.
Clearly define what type of an Instagram model you would like to be. Some of them promote traditional high fashion clothes, the others tend to be more “underground” but no less popular. Your personal style will define the brands that you will collaborate in the future.
To do this, create a couple of looks you will likely add in your portfolio. It also doesn’t mean you should follow the rules of the particular clothing style. Instagram gives you freedom: you have a personal account there and the only person who determines the rules is you. Don’t afraid to experiment and add a pinch of creativity to your outfits.
