PLEASE HELP ME TO FIGURE OUT THIS MOVIES TITLE

I watch this movie in 2004-2006,

There were 3 men(if im not mistaken). They lost their money and they suspecting a group of ladies. Hence they disguise as ladies in order to investigate them. I dont realy remember all the scene. But there is a scene when the man take bath and suddenly a lady enter the bathroom and take bath together. The lady is not wearing her glass so she didnt find out that she was taking bath with the man. Then somewhere in the movie the men fall in love the ladies
