in the course of working at the juice stand, lilly found that squeezing juice made a mess of her clothes. seeking to hide the juice stains, she designed a sleeveless shift dress made of bright, colorful printed cotton. lilly found that customers loved her dress, so she made more to sell at her juice stand. eventually, she was selling more dresses than juice, and decided to focus on making and selling what had become known as her "lillys".
