Make sure you are wearing the right bra. Has your size changed?
Determining your Bra size
Start by measuring around the ribcage directly under the breast at a constant height with the cloth measuring tape. Add 4 inches to that measurement. This dimension is your bra/band size (If the bra size works out to an ODD number go up one inch to the next EVEN number.) This should equal the circumference around the chest, directly above the breasts/under the arms.
This is the number in your bra size the “34” in “34B” for example.
Determining your Cup size
Now measure around the chest at the height of the fullest part of the breast. For the most accurate measurement, wear a comfortable non-padded bra so that your breasts are supported. The measuring tape should be held horizontal, flat on your back, and your arms should be down. Make a note of that measurement and compare it to the Bra Size from step one.
To determine the proper Cup Size, find the difference between step 2 and step 1 (step 2 - step 1.) For AA cup you would have a 1/2 inch difference, A cup = 1 inch, B cup=2 inches, C cup=3 inches and so on. So now that you have you accurate size, it’s
Time for some new bras:
Remember Curves INCREASES your cup size!
Small increases by about 1/2 cup
Medium increases by about 1 cup
Large increases by 11/2-2 cups
So make sure you take this into account when selecting your new bras.
