Thinking of starting my own clothing line.

I’m a fashion design student based in Barranquilla and I’ve been thinking of starting my own independent clothing line lately, but I’m a bit confused on where to even begin. I have my own style when it comes to designing the clothes, but I’m not really sure on what Colombian women want. I’m designing handbags and dresses for women, so I need to market my line properly and create designs that will sell, so I can earn enough to make up for my expenses. To all the fashionable Colombian ladies out there, I need some tips and insights!
