The majority of women prefer bigger breast sizes since larger breasts and a sculpted body are often deemed as more feminine and mature. Apart from this, the media also plays a vital role in highlighting and emphasizing the beauty of bigger boobs.

In this guide, we will discuss the often misunderstood D cup size and how it can look on different female bodies. We will also tell you the correct way to measure your bra size and the most perfect bras to buy to support your D cup size.

What Do D Cup Breasts Look Like?

For the longest period of time, the D size was considered the biggest bra size. This was because of the outdated system that recognized cup sizes from A to D. However, there was no standardization of what these alphabets exactly measured. It was quite a few years later that other cup sizes were introduced.

Currently, the D cup size is an above-average bra size, but only barely. It is only a size bigger than the ideal cup size C, but there are numerous sizes that go beyond the D-cup. These include sizes that go up to cup size O, which is the biggest cup size available in the U.S.

Of course, heavier boobs have their own set of challenges such as back and neck pain. Thus, D cup size is an ideal compromise for women who want bigger than average boobs and a more voluptuous figure, yet want to avoid the drawbacks of heavier bosoms.

Since D cup size is quite common, you can easily find a bra from numerous name brands in your size. But before you go buying a new bra, you should measure yourself to determine your correct size, especially if your current bra feels uncomfortable. Contrary to popular belief, wearing a bra should never feel unbearable or awkward.

You should also find out your right bra size if there is a gap between your boobs and cups, or your breasts spill over the bra. All these signs indicate an ill-fitted bra. We cannot emphasize enough the importance of finding your perfect bra size because research revealed that 80% of women wear the wrong bra size.

Here is how you can measure yourself:

  1. Take a soft measuring tape that you can wrap around your body and stand straight in from of a mirror
  2. Place the measuring tape under your boobs, on your ribcage, and wrap it around your torso making sure it’s not too tight. Note the measurement of your band size in inches
  3. Then place the tape across your nipples and around your back to measure your bust size. If you feel your boobs are sagging, wear your most comfortable bra before measuring your bust. Note the measurement in inches 
  4. Determine your cup size by subtracting the band size from the bust size. The D cup denotes a 4-inch difference
