This is how you determine your bra size
To find the right bra you need to know your exact measurements, because they are the decisive factor for the right bra. As a rule, the area under the bustline is measured first followed by the bustline itself. Your cup size is the difference between these two measurements. You should not wear a bra or clothing during the measurements.
Measure under the bustline
You can measure under the bustline in two different ways. The area under the bustline directly underneath the bust is measured, and it is advisable to stand during this measurement. Also make sure that the tape measure is placed horizontally on the skin.
In principle, you should measure under the bustline twice. The (measuring) tape should apply loosely around your upper body. It is important that it does not pinch the skin. In addition, you should let yourself inhale during measurements. You then enter the determined length. Then you should apply the tape tighter around your upper body for a second time, this time allowing the tape to pinch the skin slightly. This time you should breathe while taking measurements and enter the value.
Measure the bustline
To determine the exact bustline measurement, you should apply the (measuring) tape to the highest elevation of your bust. You should do this while standing. Make sure that the tape measure is parallel to the ground and that you breathe in during the measurement.
Measuring the bra size without measuring tape
You can also measure your bra size without a tape measure. Use some string or a cord for this. Apply the string as described above and take note of the exact length with a pen. Determine the correct dimensions by using a straightedge or folding ruler.
The right bra for a big bust
Do you have a slightly larger bust? Then it is important that your bra is the right size and fits well. As a rule, a big bust is very heavy and should be properly supported with the appropriate bra. Women with a large bust whose bras do not fit properly can suffer from various physical discomforts. When buying, you should consider that the intended support of the bra is 80 percent dependent on the underbust brace and not on the wearer of the bra, as is often mistakenly suspected. If the brace of your bra fits too loosely and slides upwards, the bust load is transferred to the bra straps. As a result, the bra straps intersect causing tension and pain in the back and neck area.
Do you have a big bust? Then you should pay attention to the following aspects when choosing the right bra:
- Wide and well-padded straps, because they do not cut into the skin like narrow straps and thus avoid pain in the shoulder and neck area
- A wider back section, because wearing comfort is then increased and prevents cutting into the skin
- A wide underbust brace, which should also be anatomically shaped and made of solid material
- Underwired bras, the braces of which surround the lower part of the bust and support and shape the bust at the same time
- A higher mid-section, because it ensures the best shape and a good hold
- The bra should be cut at the décolleté and the armpits, and should have soft cuffs to avoid incisions and skin irritation
- Dermatologically friendly and breathable material
These bras are especially recommended for large busts:
- Full Cup bras, because they provide an optimal hold. Slipping is prevented because they surround the entire bust.
- Underwired bras, because they enhance the shape of the bust and provide an optimal hold when the underwire completely covers the bust.
- Minimizer bras, because they make the bust look smaller by up to one size.
Which bra is right for a small bust?
Do you have a small bust? Then you do not need to worry about back and neck pain due to the weight of your bust. However, you should not go without a good bra even with a small bust because it can give your bust a nice shape. If you want to make your bust look larger to the eye, you can try a push-up bra, a balconette bra, or silicone bra pads.
Which bra is right for a pointed bust?
Do you have a rather pointed bust and do not want your nipples standing out from under your clothes? Then a T-Shirt bra or traditional Full Cup bra is a great option for you. Thanks to the padding of these types of bras, your nipples will be prevented from standing out from under your clothes. If you want to fill your cup a little more, you can wear a push-up bra. These will raise your bust and give it a nice shape.
Which bra is right for a disparate bust?
Women whose bust is the same size by nature are rather the exception. Although the difference in size in most women is rather small, there are also women who have a clearly recognizable difference in bust size. This is due to the fact that the nipples are also in different positions on busts of different sizes.
Although different sized busts cause no difficulties physically, many women suffer because of how they look. A well-fitting bra can provide relief. For example, busts of different sizes can be lined by bras with inserts. You can remove the insert from the cup of your larger bust and put one or two inserts in the cup of the smaller bust, depending on the difference in size.
