The author wants to provide a picture of an Indian girl assimilating to English mode of dress.
Explanation:
Below is an excerpt from paragraph 9 of the attached pdf:
"I suppose there were about a dozen Indian children in the school—which contained perhaps forty children in all—and four of them were in my class. They were all sitting at the back of the room, and I went to join them. I sat next to a small, solemn girl, who didn’t smile at me. She had long, glossy black braids and wore a cotton dress, but she still kept on her Indian jewelry—a gold chain around her neck, thin gold bracelets, and tiny ruby studs in her ears. Like most Indian children, she had a rim of black kohl around her eyes.
The cotton dress should have looked strange, but all I could think of was that I should ask my mother if I couldn’t wear a dress to school, too, instead of my Indian clothes."
