Chrissy Teigen is enjoying her last weeks of being single (her wedding to John Legend is set for Sept.) and she certainly is going out with a bang. On E!'s Fashion Police, the four-time swimsuit model admitted to never wearing underwear, claiming "I just don't like it." This inspired us to look through the office of swimsuit editor MJ Day for old Chrissy photos. We found a bunch of Polaroids from her 2010, 2012 and 2013 swimsuit fittings. Like all SI models, Chrissy tried on a bunch of suits to see what fit her the best and would be included in the issue. Here are the photos.
