My relation hid money behind a painting. (?)

Uly, how can we modify your versions to show that the person who hid the money was a female?

hide the money in her bra 😂

That's when my mother-in-law did when flu into the United States. In Amsterdam, they spotted an object in her bra and ask to show what's in there. I nearly faded out and she took out a thick pack of $100 bills. I had no idea she was traveling with money.
But seriously, the original clearly shows it was a female. So I wonder if there is a way to show it in English. Both of your versions don't explicitly say it was she.

you can say HER MONEY

that makes sense. thanks
