( ̄ω ̄) Alright, first an explanation of how bra sizes work (and what’s considered “reasonable”)
The band size is the number of inches/centimeters the area directly below the breasts (where the band will sit). It’s relevant to how big the person is. Someone thinner or more petite will likely have a smaller size, like 28, 30, or 32. Someone who’s heavier or more stocky will likely have a larger size, like 38, 40, or 42.
The cup size is taken from the number of inches around the chest at the breasts themselves is. In American sizes, one inch difference between the two measurements equals one cup size. Cup size is a measurement of how far the breasts protrude, and is not by itself an indication of size. Say someone’s band size is 30 and they measure 34 inches at the bust; that four inch difference makes them a D cup. If someone measures 28 inches at the band and 35 at the bust, they’d be a G cup. DDD cups and above are not as big as you think they are. E to H cups and above are perfectly reasonable, especially for people who are heavy.
A large cup size does not automatically mean large breasts. Band size and cup size are connected and proportional. A 32D isn’t all that big, even though it’s a D cup. A 40B isn’t all that small, even though it’s a B cup. Quick PSA here: Many people have no idea how to properly size bras, and it’s a good idea to make sure you’re wearing the correct size. A couple years ago, I though I was a 34B. After properly measuring, I found out I was a 32D. That’s the difference proper sizing makes.
Explanation/PSA over. Now for your request! (⌒▽⌒)
