* Pattern:
* Solid: A single, uninterrupted color.
* Stripes: Parallel lines of color.
* Polka dots: Circular patterns.
* Floral: A pattern of flowers or other botanical designs.
* Style:
* Formal: Plaid can be considered casual, so formal fabrics like velvet or silk could be seen as opposites.
* Modern: Plaid can be associated with traditional styles, so modern prints like geometric patterns could be considered opposite.
* Color:
* Pastel: If you're thinking of a traditional plaid with bold, bright colors, then a pastel-colored fabric could be considered the opposite.
Ultimately, the "opposite" of plaid is subjective and depends on what you're looking for in a contrasting pattern or style.
