It has been estimated that about 80% of the women wear the wrong size bra. This is not healthy for your breasts, especially if your bra is too tight. However, finding the right bra size can be a trouble for many women.
If your bra fits correctly, you shouldn’t feel any pain or discomfort wearing it. Try on different styles, because every style fits differently and can shape your bust differently. You must be able to fit comfortably two fingers under the band. If it is too tight, move the hooks to the loosest fitting eyes. If it is still tight, try the next up band size. If the band can easily be pulled away from your body or rises up your back, then go down one size. If the bra has an under-wire, it should lay flat, as close as possible, to your beast bone. With bras with soft cups, you shouldn’t have any extra, gaping fabric or spill out of the cups from the top, bottom or sides. When trying on a bra, try to raise your arms a few times. If the bra stays against your body, without lifting up or off, then it fits. If you need to, adjust the shoulder straps and pay attention to the band.
No matter what measuring system you use, you still need to try the bra on, to make sure it fits. To find the right band size, have someone measure around your chest with a tape measure, just under your breasts, and around your back. Make sure the tape measure rests flat on the skin and goes straight across your back. Add two or three inches to that measurement and this is the right band size for you. You may also try not adding anything, because the band is usually elastic. If you end up with an odd number, go up to the next even number, since bras usually come in even-sized band sizes. The determining factor should be how you feel, when you try the bra on. If the band rises up on your back, then it is too large.
Measuring the cup size is trickier. Have someone measure you again. This time the measuring tape goes on top of the fullest part of your breasts. Then, find the difference between that measure and the band-size number. The difference tells you the correct cup size. Keep in mind, that even with this measurement, it is better to try on different bras and find out experimentally which one fits. If it fits right, then that’s your cup size, even if the measure tape tells you differently.
When you go out to buy a bra, don’t rush trying on bras. Pay close attention to how they fit and feel. Be patient and go bra shopping when you know you have time for it. Try on different sizes and styles to find the right one for you.
