As I haven't read the story, I'm not certain. But based on Divakaruni's other works, themes like cultural heritage and the role of women could be possible. Clothes might be used to represent cultural identity in this story.
Many of her works blend Indian culture and traditions with modern themes. In 'The Mistress of Spices', the use of spices is not only a part of the magical element but also a connection to Indian heritage. The stories are set in different cultural contexts which she describes vividly, making the readers feel as if they are in those places.
Since I'm not familiar with this story, it's hard to give a detailed account. However, generally speaking, stories by Chitra Banerjee Divakaruni often explore themes related to female experiences, cultural identity, and the human condition. Maybe in 'Clothes', these aspects are presented through the use of clothing as a symbol. But again, this is just speculation without having read the actual story.
Magic and the supernatural are sometimes part of her themes too. This adds an element of mystery to her stories. It can be used to represent the unknown in life or the power that lies within the characters. For instance, a character might have a special gift that helps her deal with the challenges she faces in a new country or within her family.
Typically, her main characters are strong - willed women. They are often immigrants or of immigrant backgrounds. They face various challenges, such as cultural clashes, but they are determined to make a life for themselves.
The mistress of spices is definitely a central character. She is the one with the knowledge and power related to the spices. Then there are probably the customers or people who come to her for help or advice. These characters could be from different walks of life, each with their own problems and desires. For instance, there might be a young couple seeking a solution to their relationship problems through the power of the spices she offers. Another character could be an older person looking for a sense of purpose or healing, and the mistress uses her spices to try and guide them on their journey.
One of the main themes is the power of spices. In the 'Mistress of Spices Novel', spices are not just ingredients for cooking but hold magical and cultural significance. They can heal, influence emotions, and connect people to their heritage.
