White bedding is just one stuff of an all-white design. If that look is your goal, the key to success is remembering that not all whites are created equal. For giving it more classy look, mix in a variety of patterns, textures, materials and shades to help keep the space visually elegant and interesting.
And sometimes, white linens are used to provide contrast shade compared to the rest of the room. If that’s what you’re looking for, try to make your bedding pop as dramatically as possible. Go for a monochromatic color, if you want to achieve a classic aesthetic or you can try setting your white textiles against a variety of natural materials for a more modern take.
