When talking about bigger breast sizes, a D cup is normally one of the most common sizes. The D cup is just a size up from the coveted C cup and cannot be compared to smaller sizes like A and B cups. How big are D cups is a common question that many women ask. This article will offer all facts you need to know about D cup breasts.

How Big Are D Cups?

If you wear a D cup bra, this means your bust size is 4 inches larger than your band (or underbust) size. Even though D cups typically extend out 4 inches from your ribcage, not all D sized busts look the same. 

Your cup size is relative to the band size you have, and because of this, a D cup can look bigger or smaller depending on your band size. Women with a bigger band size will have D cups that appear larger and wider than women with a smaller band size.

What is a D Cup Size?

A D cup breast size should not be confused with larger cup sizes such as DD and DDD. A double D unusually measures 5 inches between the bust and band and this makes it one size bigger than the D. Conversely, a Triple D measures 6 inches from the chest and this makes it two sizes bigger.

What Bras Should You Wear as a D Cup?

As you grow older, there is a possibility that your breasts can get bigger. Finding large sized bras can be a challenge because bigger cups require more support than smaller sizes like A cup sizes. However, if you accurately measure your cup size based on a brand’s sizing chart, you will be able to find a bra that is perfect for your body type and your breasts.

If you are a D cup, here are a couple of bras that can work well for your body:

  • Full coverage bras: For complete support, full coverage bras are a D cup’s best friend. Plus, you won’t have to worry about cleavage showing, since you’ll be fully covered. Even though they are more conservative, full coverage bras still come in cute styles!
  • Minimizer bras: If you want your chest to appear smaller and closer to a B or 34C cup, add a minimizer bra to your wardrobe.

How Should a D Bra Fit?

Just like other bra sizes, your D cup bra should snug around the chest and feel comfortable at all times. The D cup bra should also offer adequate support to allow you to move around freely without the need to adjust the straps or position the cups.

You should ensure that the band of your D cup bra sits parallel to the ground. It should never move up throughout the day or tug at your skin. If your bra does this, then you should opt for a bra that is one band size wider.

Conclusion

Bigger boobs can be quite challenging to carry well or even find bras and clothes for. It is not easy to find the right bra size in an average lingerie store for women with exceptionally big breasts. The D cup is one of the most ideal among the bigger bra sizes.

This is because it is very curvy and bigger than the average breast size. However, it is not as big as E and F cups that may be more challenging to manage.
