I don't know how to post photos on here, but I have a photo from May 1932 of my father's First Holy Communion class, Saint Nicholas R.C. Church, Jamaica, New York. There are about 120 children flanked by priests and nuns. The boys from about age 10 on down are all dressed alike in white shorts, white knee socks, white shoes with white shirt, jacket, ties. The few older looking boys are wearing the same outfits with long pants. The girls are all in identical long white dresses and veils. Apparently, the sisters supplied the clothing which was either purchased or rented. Many rented because it was during the Depression and families could not afford to purchase new clothes. I can assure you everyone looks quite modest and dignified, shorts and all.
