Apollo 13 (1995)

Question: Since it was so cold on the return journey to Earth, why didn't the astronauts wear their full space suits they wore on lift-off to keep warm? The just seem to be wearing their lightweight flight overalls.

Answer: Because they need to be able to move quickly through the confined space of the module, and the full suits would be far too bulky in an emergency.

The older Apollo missions all splashed down with full suits and helmet on. Just the launch suits, not the much bulkier EVA (moon walk) suits.

Answer: According to Jim Lovell in a later interview about the mission, the crew considered putting on their space suits but in addition to them being too bulky, there was concern the suits would make them perspire too much, thus making them wet and even colder. It wasn't quite as cold as depicted in the movie, it was always above freezing, and there were no icy windows or frozen hot dogs.

Answer: In addition, since they have to leave the ship after landing, the suit filling with water would be very dangerous.

The launch abort mode was for an ocean landing, so they would have been just as vulnerable at the start of the mission. I get your line of thinking though.
