Bra Fitting Guide
your solution to finding the perfect fitting bra

At OrchardCorset.com, we know that finding just the right size bra can be extremely difficult.  Just ask one of the estimated 8 in 10 women who are wearing the wrong bra size!  We've compiled an extensive amount of information about bra fitting, brand sizing, bra styles and more to make your online shopping trip the most satisfying bra buying experience you've had!  So grab a tape measure, find your most comfortable fitting bra (and put it on) and follow the steps below.

How To Determine Your Correct Bra Size:

STEP #1.  Measure Your Underbust.  With your bra on, measure in inches just under your breasts around your rib cage at your bra line.  Ensure the tape measure is lying flat against your body and is parallel to the floor.  Round that measurement to the nearest whole number.  If this number is odd, add 5 inches; if this number is even add 4 inches. This number will give you your band size. Example: if your underbust measurement is a 33, you will need a size 38 bra.  An underbust measurement of 28 would wear a size 32 bra.

STEP #2. Measure Your Bust.  With your bra on, measure in inches across the fullest part of your bust.  Again, ensure that the tape measure is lying flat against your body and is parallel with the floor.  Round that measurement to the nearest whole number. 

STEP #3. Calculate Your Cup Size* Subtract your underbust measurement (from step #1) from your bust size measurement (from step #2).  This number will give you your cup size.  A difference of 1 inch = A cup, 2 inches = B cup, 3 inches = C cup, and so on. Example: if your underbust is a 32 and your bust size is 36, the difference is 4 inches and you would need a D cup.  In this example, the bra size would be a 36D.

Now that you know your correct bra size, go find your perfect fitting bra!

*Cup sizes through D are standardized in the U.S. and most brands will fit similarly.  However, cup sizes and the names they are given larger than size D differ greatly among manufacturers.  For example, a DDD in one brand might be an F in another.  Please check out our large cup sizing section for more information.
