Determining your bra cup size can be confusing, especially if you aren’t familiar with how bra sizing works. Many women struggle to find a bra that fits properly and provides adequate support. While cup size is just one component of finding a well-fitting bra, knowing whether you wear an A, B, or other cup size is an important starting point.
To figure out if you have an A or B cup, you’ll need to take some measurements and do a quick calculation. Your cup size is determined by the difference between your band size and your bust measurement. An A cup means there is a 1 inch difference between your band size and bust size. A B cup indicates a 2 inch difference.
In this article, we’ll go over how to accurately measure yourself to determine your bra size. We’ll also provide some quick tips on identifying common traits of A and B cup bras. Read on to learn whether you should be shopping for an A or B cup moving forward.
How to Measure Your Bra Size
Measuring yourself correctly is crucial for finding your accurate bra size. Here are step-by-step instructions:
1. Measure Underbust
– Wrap a soft measuring tape around your torso right under your bust.
– Make sure the tape is level and snug, but not too tight.
– Measure in inches and round to the nearest whole number. This is your band size.
2. Measure Bust
– Wrap the measuring tape around the fullest part of your bust.
– Keep the tape parallel to the floor.
– For the most accurate reading, inhale and exhale normally, then take the measurement as you exhale.
– Measure in inches and round to the nearest whole number.
3. Calculate Cup Size
– Subtract your band size from your bust measurement.
– Each inch of difference represents a cup size.
1 inch = A cup
2 inches = B cup
3 inches = C cup
So if your underbust is 32 inches and your bust is 34 inches, your cup size would be a B, since there is a 2 inch difference.
Identifying Traits of A and B Cup Bras
While measuring provides the most definitive way to identify your cup size, here are some general traits of A and B cup bras:
A Cup Bras
– Breasts appear small or flat against the chest.
– Little cleavage is visible.
– Bras provide light coverage and support.
– Underwire bras often unnecessary.
B Cup Bras
– Breasts have a slightly rounded shape projecting from the chest.
– Some moderate cleavage is visible.
– Bras offer more coverage and support than A cups.
– Underwire bras may be worn for extra support.
A and B Cup Sizes Across Countries
It’s important to note that sizing systems vary by country. A B cup in the United States may not be the same as a B cup in Europe or the UK. Here is how A and B cups compare across some regions:
| Country | A Cup | B Cup |
|---|---|---|
| United States | 1 inch difference | 2 inch difference |
| United Kingdom | 2 inch difference | 3 inch difference |
| Europe | 3 inch difference | 4 inch difference |
As you can see, an A or B cup in the US is typically smaller than the same cup size in other countries. Be mindful of sizing differences if purchasing bras abroad.
Common Bra Fitting Issues
Even when you know your A or B cup size, you may still struggle to find a bra that fits properly. Here are some common bra fitting problems women encounter:
Spillover
If breast tissue spills out over the top or sides of the cups, the bra cups are likely too small. Move up a cup size for more coverage.
Gaping
Loose, gaping cups often mean the bra cups are too big. Size down for a better fit.
Band Rides Up
A too-loose band that shifts up your back indicates the band size is too big. Tighten the band for added support.
Straps Dig In
Painful, digging straps can signal the band is too big and not providing enough support. Choose a smaller band size to take pressure off the straps.
Underwire Pokes
Underwires that poke out likely mean the cups are too small or the wrong shape. Try a larger, wider cup or a different bra style.
Finding Your Perfect Bra Fit
Finding a correctly fitted bra takes some trial and error. Be prepared to try various sizes and styles. Here are some final tips for A and B cups:
– Scope out selection of A and B cup bras from lingerie stores or online retailers. Styles are easier to find now than in years past.
– Try unlined, soft cup bras without underwire for maximum comfort.
– Look for demi or balconette style cups that lift breasts inward for a rounded shape.
– Consider bralettes and wireless options for lounging and casual wear.
– Enlist help getting professionally fitted at a lingerie shop or department store. An expert can identify your true size.
– Remember to remeasure every 6 months or with weight fluctuations. Bra size often changes over time.
Conclusion
Figuring out your accurate bra size and finding a proper fit takes some effort, but it’s worthwhile for support and confidence. Now that you know how to measure for an A or B cup and what to look for in these smaller sizes, you can shop for bras that flatter your figure. With some trial and error, you’ll zero in on the perfect bra for your breast size and shape.
