Wear a shirt with a high collar. Collared shirts will cover the scar without drawing any attention to your neck. Polo, oxford, turtleneck, and mandarin shirts are all good options for covering your scar.
If you have a button-up shirt, close the buttons all the way up until your scar is covered.
Drape a necklace over the scar. Try wearing chunky jewelry with large beads or rhinestones. Thick gold or silver chains also work. Try on necklaces until you find something that will lay directly across the scar.
Do not wear jewelry until the wound is healed. Talk to your doctor to learn when you can start wearing necklaces.
Wrap a scarf around your neck. This is a great option no matter what time of year it is. Even in warmer months, you can wear a light silk or cotton scarf tied in a stylish fashion.
A scarf can also protect your scar from the sun, which may help it fade faster.
