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: 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.
According to Lovell in his book, there actually were 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.
Answer: Don't remember the source (the actual movie or one of many books) but I do remember there were only two moon suits on board (the CMP, Swigert, doesn't land on the moon). I believe they decided to suffer together. I misread the question, but the option for wearing the Lunar EVA suits was considered. IIRC, they did actually wear the boots at one point.

Apollo 13 (1995)
Question: Why couldn't the crew put on their spacesuits, then go out and assess the damage?
Answer: That would involve depressurizing the command module and LEM. Given that a substantial percentage of their on-board O2 supply just got vented into space, wasting more at that point to only confirm what they already knew wasn't worth the trouble.
Answer: Even if they could go out and assess the damage, they didn't have the tools, materials, or knowledge to actually be able to fix it.

Question: How come Marilyn can't let her daughter go out as a hippie for Halloween?
Answer: Most likely because at the time, Hippies represented the counter-culture, which is/was in direct opposition to the conservative generation of the mother and not something Marilyn would want associated with the Lovells family given their high profile.

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.
