How many bras can a woman wear over 20 years from her 30s to her 50s?

Hi there,
I’m just wondering how many bras a woman can wear over 20 years and more? How many times does a woman have to buy new bras? How much has the style of bras changed over 20 years? How many times a week does a woman have to change her bras? How long can a woman wear a bra for until she has to change it?
How many bras can a woman wear over 20 years from her 30s to her 50s?
