Question: Why on earth does Marion take her bra off before putting on the white dress given to her by Belloq?

Answer: She takes off her bra because the dress has a very low back.

Answer: She was trying to "seduce" Belloq and get him drunk so she could escape. What better way to take a man's attention off your real plans than to wear a white dress with no bra on?

Answer: Strapless and backless dresses usually have a bra-like support constructed within it, and the wearer does not need to wear an additional foundation garment. Otherwise, the dress would not fit properly and would look odd, particularly a backless one.
