Okay! Now I can look at boobs in the comfort of my own home!
First off, here are some bras that are specifically made for larger cups that have 2 hooks; it looks like once you get into GG, it’ll move into 3 hooks, but it stays at only 3 hooks for up to a K cup:

And this one has 3 hooks, but is strapless and goes to a G cup:

Basically, the band is supposed to be snug (but not too tight, obviously). The most common mistake (for the saying that 80% of women wear the wrong bra size) is that the band size is too big/loose. It’d kind of be like being Kate Moss and wearing knee socks that are made for sumo wrestlers: they will fall down.
If your band is too big, it makes the straps take up the heavy (heh heh) lifting. This is what can cause indents on the shoulders from the straps.
If a bra has 4+ hooks (or 3 hooks if it’s only a D-G), it means that the band itself is not engineered correctly. There will be more force placed on the straps and the bra itself won’t be as comfortable.
I linked to the above bras because if I don’t have that specific one, I do have similar ones from those manufacturers so I know they make good stuff (for my shape, at least). For every single bra I have, I can slip both straps off the shoulders so they flop onto my arms… and my boobs stay up and perky. This is a good way to see that the band itself gives the support and lift, not the straps.
Now, for underwires, I really think that like/dislike of them may end up being tied to how your breast tissue is distributed. I’m a G cup and my mom is an A cup*. My mom absolutely cannot stand underwires of any kind. Every underwire bra she’s tried has dug into her sides horribly, even causing bruises. Meanwhile, I find underwires far more comfortable.
Besides the cup size difference, though, is where our breast** tissue is distributed. All of my boob flesh is basically front and center. She, however, has breast tissue out to the sides a lot more (some under her arms, even though it doesn’t look like it; just looks like she has normal front boobs). When she went for her first mammogram, she had far, far, far more pain than expected because they need to get all the breast tissue between the plates, which meant they pulled the side breast tissue very hard, causing her pain that lasted for almost 3 months. I’m betting that if you have a wider spread of breast tissue, underwires are more uncomfortable because they dig into the breast tissue itself. Meanwhile, boobs like mine are able to be completely contained in the underwire.
So the downside is that if I pay full price for a bra, I’m looking at minimum $50 per bra, which sucks. But the upside is that I can have a “stripper size” (34G) bra that is comfortable, have no back, neck or shoulder pain, and my boobs are up high and proud. I’d much rather that than having a bra that cost $25, feels awful and has my boobs sag and spread.
- you bet your bippy we’ve wondered where my rack comes from!
