If you're looking for a career in the industry of design, more than anything, you need to demonstrate your talent. There's a lot of trust involved, whether it's an interior designer, or you're designing clothes for someone, or you're being a stylist, what you're talking about is a person's extension of themselves through their home or through their clothes. The only way they're going to trust that is if they can see a demonstration of your work, so as much as possible, you want to build a portfolio. Ask a friend if you can help design their house, or ask a friend if you can design her bridesmaid dresses. It's all about demonstrating your talent, because design, a lot of it is about trust. You want to have a portfolio so that you're not just talking about what you have the potential to do, you're showing them what you have the potential to do. Design is all about aesthetic. It's visual. Make sure that you get a portfolio in order to knock it out of the park.
