• Wearing a graphic tee with another graphic piece: That's a clash. If your jacket or shoes have big logos, skip them.
• Over-accessorizing: A graphic tee is already a statement. Don't pile on chains, bracelets, and a watch. One or two pieces max.
• Ironing the print: This is a classic mistake. It can melt the graphic and ruin the tee. Always turn it inside out and iron on low, or just avoid ironing altogether.
• Buying the wrong size: If you're between sizes, size up for a looser fit, but not too much. A medium that fits well is better than a large that swallows you.
