We have set up an online store and are getting close to launching but have to work through the website errors or things we can't figure out. The main issue we are having is figuring out how to add several colours and sizes for the same product. For example we have a T-shirt which we have in black and grey and we stock 3 different sizes. Currently we have each one added to the product list and in the heading we put the size however for a customer browsing our store this looks very unprofessional and confusing. Any help you can provide would be great.
