You can not make something "without" design.

You can find something ugly. You can try to make something more aesthetically appealing for a certain group of people.

If these people have "aesthetic appeal" as a criteria, you can have a competitive advantage. Unless you are selling jewelry or other luxury products.

But most of the time, aesthetic appeal is not a key decision factor. People may not decide really rationally but they are not going to buy something without any function that solves a real problem for them.
