Kadas are a type of traditional Indian bangle that is typically made of metal. They are worn around the wrist, often along with other bangles. Some common styles of kadas include:

1. Simple style: a plain, solid-colored metal bangle.
2. Ornate style: a kada with intricate designs and decorative elements, such as gems, filigree work, or enamel.
3. Chunky style: a wide, heavy kada that makes a bold statement.

Kadas are typically worn with traditional Indian outfits, such as saris or salwar kameez, and can be worn for special occasions, such as weddings or religious festivals, or for everyday wear. The design and style of the kada can vary widely, with some styles being more elaborate and ornate, while others are simple and understated. Kadas are often considered a symbol of married status in Indian culture.
