I am curious to know if women who dress provocatively are more or less likely to be victims of sexual assault. The best way to find out would be to conduct a study in a country where a considerable number of women wear more modest attire and a considerable number of women do not, and then compare the sexual assault statistics between the two groups. Conducting the study in the same country should reduce the influence of other variables, such as cultural differences or differences in reporting. A potential country to use for this study could be Malaysia, where many women wear the hijab and many do not. The study should also consider other factors, like the age of the perpetrator and victim, time, and motives.
I was unable to find any statistics about this topic. Although there are a lot of results for how people view revealing clothing and sexual assault, none of the results show a direct connection between the two. The one study I did find which had relevant results was called She Dresses to Attract, He Perceives Seduction: A Gender Gap in Attribution of Intent to Women’s Revealing Style of Dress and its Relation to Blaming the Victims of Sexual Violence and it surveyed respondents about whether they liked wearing revealing clothes and if they experienced four types of sexual victimization, then looked for correlations. This seems to be a complicated way of obtaining data, when a more direct way would be to look at the clothing worn by victims of sexual assault. The study also didn't focus on the causality between the two, as is clear from its title.
