What does Maya wear to the church's Easter Sunday celebration

From the text:

"The dress I wore was lavender taffeta, and each time i breathed it rustled, and now that I was sucking in air to breathe out shame it sounded like crepe paper on the back of hearses. As I'd watched Momma put ruffles on the hem and cute little tucks around the waist, I knew that once I put it on I'd look like a movie star...when people saw me wearing it they were going to run up to me and say 'Marguerite,forgive us, please, we didn't know who you were,' and I would answer generously, 'No, you couldn't have known. Of course I forgive you' "
