How much is too expensive for one bra ?

When you are old and out of shape don’t forget girdles are 3.98.

Anywhere over 40 dollars 

Depends on what you get for your money. If I've worn it once a week for 10 years and it's still going strong, I've gotten at least $50 worth of wear from it. 

I've only ever paid more than £50 for a bra once and that was for my wedding day.
