First of all, I would like to address the fact that no woman has ONE bra size. Wouldn't that be nice if we could just buy bra's that are appealing to us without taking the time to to try them on? Well sorry ladies, it just doesn't work that way. We see it all the time. Woman come into the store and buy bra's in "their size" without trying them on first and most of the time they come back unsatisfied.
So what are some reasons for this madness?
1. All companies cut their bra's using their own measurements
2. All styles are cut differently. For example, full coverage bra's run differently than demi cut bra's, etc.
3. The material that the bra is constructed with plays a big roll. Does the cup have a lining in it? Is there a pad?
So then why take measurements at all? Measurements really just give you or the professional who is doing your fitting a place to start. Honestly, as a professional I come up with a more accurate size by looking at you than I do with measuring tape and no, I am not incapable of when it comes to the tape.
How do you get measurements using measuring tape? Make sure you are wearing your most supportive unpadded bra for this process in order to get the most precise results.
Step 1: Take the measuring tape and measure directly under your bust line with the tape parallel to the floor. Round up or down to the closest whole number of inches. Add 3 to that number and this will give you your likely band size.
Step 2: Measure around the fullest part of your breast with the tape parallel to the floor. Round up or down to the nearest inch as you did with your band size. Subtract your band size from this measurement. Use the chart below to match the difference with the likely cup size.
Difference (inches) Cup Size
0-1 A
1-2 B
2-3 C
3-4 D
4-5 DD
5-6 DDD or E
What is the best way to bra shop? Find a small boutique that performs bra fittings. Here they will be able to spend proper amount of time with you that you need. Make sure it is a place that you feel comfortable with because bra fitting can be a vulnerable experience for some ladies. Also, make sure that you trust the employee's there and are confident that they have you're best interest at hand and nothing else.
