How can I be a successful fashion designer

Leverage social media to post your work and make yourself more known to the world, and try to find local or remote opportunities to apprentice under more established, successful designers from which you can learn the business.

To start being successful....which is a generic term...needs to have a better and clarified definition coming from you, which is a deep thought.

One or maximum should define your success, broken then into small success of milestones....

Start with that ....definition of success...of what means to you and will that definition keep you awake, while you are sleeping ,will that definition , keep you focussed , when the world around is shouting. will that definition keep you holding the ship , in the worst of storms...that definition.
