I've owned many patterns over the years but I love solid white. Food looks beautiful on a solid white plate. The food is what stands out without the distraction of a patterned background or color. Using solid white dishes lets you decorate your table according to the season. You can change the mood of the table by using different colored placemats, napkins, and glassware.
For formal dinners, I love my timeless Lenox Eternal china. It is solid off-white, with an elegant gold border. I have had this china for many years and have never grown tired of it.
