I'm interested in fashion - what good careers are there?

Firstly, you need to have a think about how serious you are. Because if you are REALLY serious about a career in fashion, you will be willing to work your way up, and that does means starting in jobs like retail or production line (factory), you can't just jump into the perfect job. Also, you will need to go to either college or university to get some training behind you. Designers and dressmakers will not employ someone who has either no experience or training, or who hasn't shown a willingness to learn. Look into further education and see if there are opportunities there that interest you. Also, contact businesses and ask if you can do work experience with them. Anything like that will help. But the bottom line is that you must think again about your feelings towards shop work and factory work. They are excellent starting points that you can work up from.
