Yes, you can choose whatever design you want if you opt for WordPress ecommerce website. In fact, WordPress offers countless design options (both free and paid themes). You can also create your own custom theme/design from scratch. In general, for most of our clients, we recommend purchasing a ready-made theme/design as the cost is lower compared to building something from scratch. If the client’s needs are very specialized, then we discuss different solutions. But always be aware that a specialized solution comes with higher costs in terms of both creation and maintenance.
