If there are gaps between the cup and your breast, you're wearing a cup size too big. If you find your breast spilling over the top, side, or bottom of the cup, you most likely need to go up in size. You also need to consider a larger cup size if the underwire or bottom of the bra is resting on your breasts.
Once your breast is pulled forward, if the tissue is not completely in front of the wire, you need to go up in your cup size. For every 3/4 inch of breast tissue under and behind the wire, go up one cup size. If you have never been fitted, it is likely that you will need to go up several cup sizes.
There are many ways in which the wrong size bra can contribute to breast pain. If your bra is too small, it can dig into your breasts — if it is too big, your breasts may have too much room and can become prone to bouncing around, contributing to tenderness.
For every band size you go down, you have to go up a cup size to compensate the difference. Let's say you wear a 34B, the cup fits but the band is too big. You measure a 30 band size. A 30 band is two band sizes smaller than the 34 band.
Ill-fitting bras have also been associated with neck, back and shoulder pain, bad posture, and rubbing and chafing leading to skin abrasions. We also see ill-fitting bras causing permanent changes to the body, such as deep grooves in the shoulders caused by pressure from the bra shoulder straps.
According to a survey conducted between 1992 and 2013, the average bra size in the U.S. has increased from a 34B to a 34DD, and now just six years later, the average has shot up to a DDD — that's the largest compared to any of the other countries studied.
Larger the band size, the larger the cup. Therefore, the cup of 34B is the same as 32C or 36A. Knowing your sister size will help you in finding the right-sized bra for you.
A 32C is one cup size smaller than a 34C. That also means a 34 is two cup sizes bigger than a 30C, and so on.
A 34C and a 32D are actually the same size cup size.
In order to determine if your cup size is too big or small, look to see if you have an extra bump of breast tissue at the top or at the sides of the cups or if you have a wrinkle in the cups or extra space in the cup.
An obvious sign that the cups are too small is if the underwire presses in at the sides of the breasts or if you have red marks on your breasts when you take your bra off in the evening. The underwire should enclose and cradle the breasts; it shouldn't pinch anywhere. If it does, you need to go up a cup size.
The bra curling up under the bust is a sign that your bra does not fit properly and it usually means the bra back band size is too small. Our bra specialists advise – “Try a larger bra back size, avoid deeper bands and consider an underwired bra.”
While it's really difficult to precisely determine the standard breast size in the U.S. (or anywhere in the world, for that matter), wedo know that the average breast size in America is a 34DD.
There's a good reason why most people have voted C Cup as the ideal boob size. The C Cup breast size denotes positive factors such as young age, the right estrogen level and high fertility. C Cup essentially signifies the best matrix in terms of mate selection, as perceived by subconscious evolutionary systems.
No matter the type of bra, the band should fit comfortably around your body, snug but not tight. Remember to always start a new bra on the loosest hook and hook tighter as the band stretches over time.
As a general rule of thumb, it's important to have a healthy rotation of bras at the ready so that you're never left blindsided — and bare chested. All things considered, we'd suggest owning 11 bras in total in a couple of distinctive styles that range from everyday to on-occasion.
How often you need to wash your bras isn't an exact science. But dermatologist Alok Vij, MD, says that as a general rule, you should wash them after every two to three wears.
If your band and underwire are the right size, then the center gore should lay flat against your sternum. You should not be able to move it easily, but it also shouldn't press too hard on your chest. If the center gore of your underwire bra does not lay correctly, then the cups are too small or the band is too loose.
Cups that are too small will result in spillage, so try going up a cup size. But also consider the shape of your breasts. Breasts that are fuller and rounder at the top will need more coverage than breasts that are firmer at the bottom. Choose styles that provide generous coverage to avoid overspill.
Stand upright without a bra on, and using a measuring tape, measure around your back and under your bust, where the band of a bra would usually sit. Make sure the tape is going around in a steady, even line. It should feel snug, but not tight. Measure in inches: if you land at an even number, that is your band size.
That number represents your cup size. For less than one inch you are a AA cup, for one inch you are an A cup, for two inches you are a B cup, for three inches you are C cup, for four inches you are a D cup and for five inches you are a DD cup.
Actresses Angelina Jolie, Jennifer Aniston, Leah Remini, and Valerie Bertinelli also wear 34C bras.
