I can not cannot understand some old movie lines...

Last night, I saw a French classic movie, "Change Pas De Main" with English subtitles last night.
But However, I can not cannot understand some of movie lines subtitles so far. Here is are some of them a few part of lines:

A："My poor woman! Those two milliard income a year..."
　 "You wear them on your face!"
B："I don't even wear them on my back."
　 "I don't give a shit about money!"

What's meant  by "You wear them on your face!" and "I don't even wear them on my back."?

Can anybody anyone help me?

The conversation is talking about how much money this person is earning in a year.  "You wear them on the face" is a sarcasm by the speaker to the other.  It means that the person is so rich that you can see it in their face (expensive makeup, earrings, necklaces etc)

The answer is a retort.  Another sarcasm.  You can't wear such stuff on your back even if I have them.  Hence the comment, "I don't give a shit about money". It can also be taken as sour grapes.
