Bright Maidens: Scapulars: I Feel Weird

The “Bright Maidens” were originally three from the oft-mentioned, widely-speculated upon demographic of young, twenty-something Catholic women. Now, we all take up the cross to dispel the myths and misconceptions. Welcome!
Topic: Scapulars
Scapulars: I Feel Weird

An older lady at a Holy Hour recently cornered me in the bathroom to tell me about her life and Catholicism.  She urged me to start wearing a scapular, and explained how her mother, who always wore one, died on a Friday, which means she was only in Purgatory for one day.  According to this lady, the Virgin Mother visits Purgatory on Saturdays and takes all the souls who wore scapulars to Heaven. 
Confession: I have very limited knowledge about scapulars.  I don’t even know if what that lady told me about them is true.  I’ve seen them sold in Catholic stores, and sometimes they come in the mail, but the promises about Purgatory and Heaven?  What is the history behind them?  Where do they come from?   
I deliberately didn’t research anything about scapulars before this post because I wanted to present my honest confusion and lack of knowledge about them.  I think other Catholics may have the same feelings, which may be born from ignorance, hearsay, and lack of context regarding scapulars.  This is an aspect of Catholicism that makes me feel…weird. 
I’m excited to read and learn more about this topic from my fellow Bright Maidens and contributors.
