Rider's Bra Sizing

To work out your size you need two dimensions: the measurement around the bust and under the bust. It is the difference between these two measurements that determines the cup size. Use a standard dressmaker's tape measure. For best results, have someone else measure you. If between sizes, buy the larger size.

1. Band Measurement - Take a snug measurement around your rib cage, under your bust and then add 5".
Example: 29" + 5" = 33" (between size, so go up one to 34")

2. Bust Measurement - With bra on and clothes off, take a loose measurement around the fullest part of your bust and then add 5".
Example: 37" + 5" = 42"

3. Determine Cup Size - Subtract Band Measurement (from Step 1) from Bust Measurement (from Step 2).
Example: 42 - 34 = 8"

If difference is: 8"9"10"
Cup Size is: C D DD
