Playful patterns can add visual interest and elevate a simple item or outfit. They can be small and subtle, or big and bold. On different legs of your style journey your style can be pattern-rich, pattern-poor, or void of patterns entirely. Follow your mood.
Stripes, dots, animal prints, plaids, and florals are the classic patterns. When pattern mixing, use a unifying colour to keep the outfit harmonious. Patterned scarves, belts, or shoes are effective accents if the rest of the outfit is in solid colours.
If you are pattern-averse but still want to break patterns into your style, keep them neutral, subtle, low contrast, and with lots of solid space between large motifs. Wear them away from your face. Or use them as a layering piece under a solid topper.
