What type of clothing is considered inappropriate for the elderly?

Clothes made of cotton material are often recommended for the elderly because cotton is breathable, soft, and comfortable against the skin. However, the issue with multiple types of fastenings is significant. For elderly individuals, especially those with compromised mobility, cognitive difficulties, or those who may have arthritis, clothing that requires complex fastening — such as buttons, zippers, or toggles — can be challenging. This difficulty can lead to frustration and may even discourage them from dressing independently, which can impact their dignity and self-esteem.

In contrast, options like loose-fitting pants and non-slip, slip-on shoes are suitable for the elderly, as they prioritize comfort and safety. Loose-fitting pants allow for ease of movement, while non-slip shoes help prevent falls. Silk blouses, while potentially bright, may not be practical due to their care requirements and the potential for being less durable. Thus, it's the complexity of multiple fastening types in option C that makes it the inappropriate choice for elderly clothing needs.
