Great movie in all categories and very moral by today's standards particularly.
There is no explicit nudity and no sex scenes.
One of the rules of the saloon posted on the wall says "The girls in this saloon are ladies - treat them that way unless they say you don't have to."
The lead female character is very buxom. Her tight outfits, while not overly revealing, accentuate her figure. The dancing girls and entertainers often wear costumes that show their legs and cleavage.
A female character raises her skirt to show her garter belt.
Patrons of the saloon charge the stage at the end of each set to grab the dancing girls and have to be forcibly pushed back.
A male and female character become increasingly close, he seemingly intoxicated by her aroma, which leads to them kissing.
