saw a post where someone fundamentally misunderstood bra sizes so i wanted to help clarify
a common misconception about cup size is that a DD is just the size of a boob. however, the way it actually works is that cup size is a relative measurement.
the first measurement you need is the measurement all the way around your ribcage, right below your tibbies and this measurement is the band size. the second measurement you need is the measurement around your chest where your tibbies stick out the most and this is called the bust measurement.
the difference between the band measurement and the bust measurement determines your cup size where AAA is a difference of zero inches and a G is a difference of 6 inches.
THIS SYSTEM IS INCREDIBLY CONFUSING!!! and it often leads to a lot of people not understanding which bras they need!
this is why a lot of people get mixed up when someone has a size of 34DD vs 44DD because they are comparing two entirely different body types that happen to have the same cup size in name only.
hope this helps!
it's also super important that when you're measuring your cup size, you should bend over so they hang perpendicular to the floor! then you gently wrap the measure around the fullest part of the breast only tight enough to stay in place without digging into the skin much, that should give you a more accurate cup size to pair with your band size!
I DID NOT KNOW THIS EITHER THANK YOU
