Depends on how you define "a lot." On lingerie night, 100 percent of the men and women who go to the official show in the indoor bar (Nice Shoes) have to dress up to get in. About 30 percent of the people at the outdoor bar (PatyO's) after the show will be in lingerie. The other nights just take place informally at Paty'O's, and participation depends on the group. Roughly 25-50 percent of the women will be dressed up each night, and 10-30 percent of the men. White and red nights will have the most since they're officially listed on the TTR website, and the other informal themes like schoolgirl or superhero will have the least since they're organized by people on this site. It's totally fine to wear "normal" clothes any night you want. If you do dress up, you'll immediately find the other CCC members, and you'll have curious people wanting to take pictures and find out about what's going on. The best strategy is to take two options for each night--a normal one and a theme night--and you can decide what you want that day.
