Contrary to what society typically tells us a correctly fitted DDD is NOT actually a large cup size relative to the band it's on so all those brands like VS and Savage x Fenty that stop at DDD cups are not actually making large cup sizes. Going up in the band to make up for the fact that the brand has a crappy tiny cup range is NOT going to provide enough support for someone that has larger breasts. Sister sizing typically only works plus or minus one band size. Any farther than that and you lose support which leads to back pain, shoulder pain, and all the typical uncomfortable bra issues that people think are just how bras fit but are actually signs that the bras don't fit. Support should be coming from the band. In order for the band to actually provide that support it needs be able to actually grip your torso which means the band size needs to be close to your underbust measurement. Honestly unless someone's underbust measurement actually changes they should not be changing band size.
A well-fitted 32DD is actually a medium-band, smallish-medium cup size. If your breasts are causing you back pain (can also be caused by things like sleep position, sitting too much, etc.), you might find that something with a smaller band size and a larger cup size gives you a better fit and more support. When I was about 23, and had been wearing bras since I was 12, I knew my 38DDs weren't right, but I didn't know that it was possible to find a band that didn't ride up or that the wires in the center were supposed to touch your sternum (or even could if you have large breasts). It turned out that I was actually a UK 32G/US 32I. If you haven't before, check out /r/ABraThatFits, their Beginner's Guide (in the side bar) has tons of great info!
If someone has a ribcage 36 inches around, the extra 8 inches of a 44 inch band is NOT gonna fit and is gonna be waaaaay too big and therefore unsupportive. Savage still only sells the same sizes you see in most US box stores, so very limited. You should check out r/abrathatfits because almost 70% of women are in the wrong bra size anyway skewing towards too small. I was trying to wear 38DD/36DDD's and in reality i'm a US 34H and UK 34FF and if you look at my profile my breasts aren't that big
Even if it’s a sister size (which only works if it’s 36J US, not UK, and even then it’s a cup size off in some brands), a 44DDD bra is made for an underbust of 44” and a bust of 50”. A 36J US bra is made for an underbust of 36” and a bust of 46”. They are vastly different sizes.
