A 36C bra is equivalent to a 14C in Australian/NZ sizing, a 75C or 80C in European sizing, and has sister sizes like 34D and 38B (same cup volume, different band), with 34D being a tighter band and 38B a looser band, depending on the brand.
A 36C bra size in the US/UK is equivalent to a 14C in Australian (AU) sizing, using the band size 14 with the same C cup. This means you'll look for a size 14C when shopping in Australian stores, with the band size corresponding to the UK/US 36.
Especially in this day and age, 36C is a ``average0 breast size for most women of at least average or larger (usually taller, not curvier) builds. It is a size where getting bras is simple off the rack and is fairly easy to find.
An Australian size 36 (AUS 36) typically corresponds to a US size 6 (women's) or a US/UK size 36 for men's bottoms/waist, which is around a 30-32 inch waist for men, while for women's footwear, AUS 36 is a European size 36, roughly a US 5.5 or UK 3.5/4, so it depends on whether you're looking for clothing or shoes and if it's men's or women's.
A C cup is generally considered an average to slightly above-average or medium breast size, offering good shape and curves without being excessively large or small, but its appearance depends heavily on your body frame, as it represents a 3-inch difference between bust and band, varying by individual. While A/B cups are smaller and D/DD+ are considered larger, C cups sit comfortably in the middle for many, though perception of "big" varies globally and by personal preference.
The 36C size strikes a harmonious balance between band and cup proportions. The "36" represents the band size, indicating the measurement around the ribcage just below the bust, while the "C" signifies a moderate cup volume, reflecting the fullness of the breasts.
Average Cup Size
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.
Find your Sister Size
"Down" means the opposite - one actual size smaller and one letter name larger. For example, if you wear a 38B, your Sister Size Up would be 40A, and your Sister Size Down would be 36C. You can wear either one of the Sister Sizes and still have the same cup volume as 38B!
The "two-finger rule" for bra fitting is a quick test to check if your bra band is the right tightness: you should be able to comfortably slide two fingers (stacked or side-by-side) under the band at the back, but not much more, indicating it's snug enough for support without being too tight or riding up; the band should feel supportive and stay level, with straps only providing slight lift, not carrying most of the weight.
Asian and African nations have the smallest, with predominantly B and A cup sizes being most common. Australia is way down the list: in 2020, the most common Australian bra sizes are reported to be 14C and 12D, and while this is the average across all ages, there really is no such thing as the “average” woman.
A US size 14 generally corresponds to a European (EU) size 38, but it can sometimes be a 36 or even a 40 depending on the brand and country (UK 12-14, Australia 14), with measurements often around 38-40 inch bust and 30-32 inch waist for the large/size 14, so it's always best to check specific brand charts.
For example, if you measure at a size 34D, your sister sizes are 32DD and 36C. They are the sizes directly left and right of 34D size in the chart. These bras hold the same volume, but at a different band size. At 32DD you'd have a much firmer band, whereas 36C would be a more relaxed feel without the loss of support.
To measure your Australian bra size, find your underbust band size by measuring snugly around your ribcage (in cm) and your bust cup size by measuring loosely around the fullest part of your breasts (also in cm); then, subtract the band from the bust measurement, where a 12-13 cm difference is an A, 14-15 cm a B, 16-17 cm a C, 18-19 cm a D, and so on, using standard AU band sizes (like 10, 12, 14) and converting the difference to a letter cup size.
What are the Bras Perfect for 36C Size?
It turns out, over half of women polled thought a C cup was the perfect fit. At the same time, close to 26 percent preferred a B cup. Nearly 2 percent said an A cup was their preferred breast proportion. Notably, men also agreed that a C cup was their ideal size.
Mammary glands are influenced by hormones activated in puberty. Shrinkage (involution) of the milk ducts is the final major change that happens in the breast tissue. The mammary glands slowly start to shrink. This often starts around age 35.
Even with the best care, bras lose their shape over time and don't support you as much as they should. In fact, if you are wearing the same 2-3 bras every day, you should be retiring your bras after just six to nine months.
Eg: If you wear a 36C, your sister size down will be 34D.
A C cup typically indicates that the bust size is about 7.5 centimetres more than the band size. For example, if your band size is 80 centimetres and your bust measures 87.5 centimetres, you would be a C cup. However, when discussing breast implants, we often refer to cubic centimetres (cc) rather than cup sizes.
36C is a bra size that represents a moderately sized band with a C cup. In terms of breast size, it is considered to be in the average range. The number 36 refers to the band size, which is the measurement around the torso just below the breasts.
For many women, a C cup can symbolize a balanced, natural appearance that aligns with their ideal body image. It is often associated with femininity, attractiveness, and confidence, especially when women feel comfortable with their proportionate curves.
The term “big” is one of the most subjective descriptions when discussing breast size. There is no single cutoff, such as “D cup and up is big,” because cup size isn't a standardized measurement of breast volume.
