It's common to conclude that pillow cases and pillow shams are the same products. They both cover your pillow for protection and add style to your bed. Similar in look, but different in design, one should be used to prevent your pillow from staining, the other for decorative purposes only. The case is a protective cover, the sham a statement of style.
The difference between the two is subtle, but choosing the wrong one could affect your pillows and how well you sleep. Shams and pillowcases tend to be made from different materials, because cases are suitable for sleeping on, whereas shams are best left to be looked at. Whether you've bought a new duvet cover and want a couple of cases to go with it, or are looking to switch up your sheets to give your bedroom a whole new scheme, knowing whether you should buy a pillowcase or sham is key.
