Practically speaking, putting on jewelry last is a good idea because it can prevent your clothing or makeup from getting caught on your jewelry and potentially damaging it. For example, if you put on a necklace before your shirt, the clasp or pendant could get caught on the fabric, causing the necklace to break or your shirt to tear. Similarly, if you put on earrings before applying makeup or styling your hair, you may accidentally get product on your earrings or snag them with a brush or comb.
In terms of safety, taking off jewelry when you get home can help prevent accidents and injuries. For example, if you wear long necklaces or bracelets while cooking or cleaning, they could get caught on something and cause you to trip or fall. Removing your jewelry when you get home can also prevent damage to your pieces, such as scratching or tarnishing, that can occur from exposure to household chemicals or rough surfaces.
Etiquette-wise, taking off your jewelry when you get home is a sign of respect and consideration for others. For example, if you wear large or noisy bracelets or rings, they can be distracting or annoying to others in quiet or professional settings like meetings or libraries. Similarly, if you wear scented oils or perfumes on your skin or jewelry, they can be overwhelming or cause allergies in others.
In conclusion, putting on jewelry last when dressing and taking it off first when you get home is a good practice that can help protect your jewelry, prevent accidents, and show consideration for others.
