I am a school librarian, and this dress is absolutely perfect for work. I can squat down to shelve books without worrying about my unmentionables showing. The neckline is easily adjustable--you can make it low-cut or more conservative without any pins or clips. I am 5'6", 140 pounds, and the M is a perfect fit. Length hits right at the knee. I pair this with leggings, boots, and a cropped cardigan in the winter. In the summer, I just throw on a pair of ballet flats, and I am good to go. I wash it in the washing machine and hang to dry. I bought this about a year ago, and I've probably washed it 20 times so far. No rips, holes, or snags. I bought the black dress and the royal blue dress, and I'm back today to buy some more.
