How to get the right bra size? Any ideas?

• Are you a different bra size in every shop?
• Are you different bra sizes in the SAME shop?
• Have you been measured for a bra and found that once you put on an ounce of weight you stretch the lot and are now back to square one?
• Do you find that your expensive bras instantly turn into an ill-fitting different size in the washing machine?
• Have you ever caught sight of yourself in the mirror in a tight top and found that you have TWO BOOB syndrome.

If you answered yes to any or all of these questions then welcome to my world.

And I'm only a C cup (I think). How are you bigger boobed ladies coping? And is there a solution to this problem?
