When choosing between metal and plastic collar stays, it’s essential to consider durability, appearance, cost, and the level of formality. Metal stays are durable, offer a firm, crisp collar, and are ideal for everyday use in professional settings, though they come at a higher cost. Plastic stays, on the other hand, are budget-friendly, lightweight, and easy to replace but may not provide the same longevity or collar firmness. Discover which option suits your needs best based on your lifestyle and style preferences.
