Her style of dress typified the period, and the character is still a fashion icon. John Bates was brought in as the costume designer for Emma Peel in the second half of the fourth series. He created a wardrobe of black and white op-art mod clothing and miniskirts. Before this, people had believed that lines, circles and other bold patterns would not work on the television cameras of the day. Episodes were filmed before the miniskirt had even become a mainstream fashion statement. Bates had to stop leaving hems on the mini skirts because the production team kept lowering them again. He also licensed his designs to several manufacturers under the "Avengerswear" label and these pieces were sold in various shops throughout the country. Diana Rigg is often remembered for the leather catsuit she wore early on in her first season. Rigg disliked wearing the leather outfit, so Bates designed softer stretch jersey and PVC catsuits for her instead.
