5.5. Product Attribute Sets
An Attribute Set, in Store Manager for Magento, and in Magento itself, is a collection of Attributes.
Suppose we are selling a shirt. In addition to the default Magento Attributes, you want to display additional information to your Customers, in the front-end, such as color, shirt size, manufacturer (brand), material (ex. cotton, wool, …)
An Attribute Set is simply a Categorized product type, within your online Store. Shirts will have different attributes than watches, or sunglasses. Before beginning inserting products directly under the "Default" Attribute Set, or in the same group, think ahead, about what attribute sets are planned to be used. Then categorize, and assign attributes to their Attribute Sets, afterwards adding their relevant products.
