If you know your average bra size, then its as simple as that. All you have to do is enter the number and the letter. For example, if you are a 36 DD you would enter “36” in the rib cage drop down and “DD” in the cup drop down.
As well, if you are any other double digit cup size besides a DD, we recommend going up a cup size and the BreastRest™ team will take it from there. However, please Contact Us with any inquiries or clarification.
1. Band Size
Take the measurement of your rib cage + 5 inches = band size
Ex: 29″ + 5″ = 34″ the band size is 34; attach at the middle of the hooks
Ex: 31″ + 5″ = 36″ the band size is 36; attach at the middle of the hooks
Ex: 30″ + 5″ = 35″ the band size is 35; attach at the biggest of hooks
2. Bust Measurement
Measure completely around the fullest part of your bust (at nipple level). This is your bust measurement. If this measurement falls on the ½ inch, round up.
3. Cup Size
Subtract the band size (step 1) from the bust measurement (step 2).
This number equates to the letter of your cup size:
| 1 inch
| 2 inches
| 3 inches
| 4 inches
| 5 inches
If the front center of your bra does not lie flat against your body, the cups may be too small. Try going up a cup size for a better fit.
If the back band is riding up, it may be too loose or too big. Try adjusting the closure or going down a band size.
If the straps leave marks long after you removed them, they may be working too hard. Try tightening your band to take some of the pressure off, and loosen the straps. If this doesn’t help, the cups may be too small, and you may need to go up a cup size.
If you spill out of the top of your bra or bulge out of the bottom, the cups are too small. Try going up a cup size.
If the cups gap or pucker, either the band is too loose or the cups are too large. Try tightening the band or going down a cup size.
If the bra straps are always on the run, the band might be too loose or too large. Try tightening the bra band or going down a band size.
If the underwire in your bra is digging into your sides or does not lie flat below your breasts, the cups may be too small. Try going up a cup size.
