Antonyms for the word "window-dressings" are simple, minimalistic, and unadorned. Window-dressings usually refer to the decorative items placed around windows to enhance their aesthetics. However, if you're someone who prefers a clean and straightforward look, you can opt for no window-dressings at all. This style not only provides a minimalistic look but can also allow more natural light to enter the room. Additionally, if you're looking for privacy, you can choose to install blinds or shades that are functional in design and do not require additional decorative elements. This way, you can maintain the privacy of your space while still maintaining a simple and clean look.
