Smaller bra size?

It is different for everyone. My band size goes down but my cup size doesn't usually go down much (and I'm a G cup so that sucks really).

Some women do lose cup size and some don't, and I know in theory it is fatty tissue and it should leave, but it doesn't always, depends on genetics largely for that component of it unless you get super super thin.

eta: I am hoping this time is different, I would love for them to get small enough for me to buy underarmour sports bras and to shop regular stores for bras (I have trouble finding my current size even at the big women stores).

I don't get it tbh. I just want your explanation... Why do so many women not like having big boobs? I don't really get that concept. Which exactly is this?

Here are the top 3 I can think of:
1. For some women it causes back pain (this can be mitigated for many with the proper sized bra, but not for everyone.) I am not one of those large busted women with that problem. My sister, who has another cup or so on me at a similar weight does.
2. Having large breasts has been deemed by society as a sign of being fat. This thread isn't bad, but many other breast size threads start insulting women with larger breasts saying it is all fat and they'd rather be "healthy" than fat with big breasts. Breast size is a lot more complicated than that, and there is a ton of variation. There are some people who gain weight in their breasts, and other women who's size hardly changes with weight gain. They are destined to have a large chest even at low weights or body fat percentages. There are also plenty of women with small rib cages and large breasts who have a very difficult time shopping for bras, but mainstream stores send them to plus sized stores to shop for bras. And even those do not fit. (I am one of those, even though I am at border of plus/regular at size 14-16, Lane Bryant doesn't have a bra to fit me. All are too big in the band and too small in the cup.)
3. Having a larger bra size makes it difficult to shop for bras. You need to go to specialty stores and bras are pricey. For me, a cheap bra means under $50.
4. Having large breasts is deemed as being slutty or not classy. I.E. you are a porn star or easy.

Our society has sexualized breasts so much, you can't just have them without people making assumptions. In a way breasts are a feminist issue. Think about all of the breast feeding controversy. Women aren't supposed to breast feed in public, because people might see their boobs!!!! Aahhhhh!!!! How will the men control themselves with bare breasts on display?

I have had sketchy guys ask me my breast size in the context of "flirting." Or just ask to see them. And many other women have had much worse experiences.

Since I have started my weight loss journey I have had about 6 or 7 people (all females)say something to me about getting a breast reduction if I don't loss weight in that area. I know I will Lose some weight but I was big when I was smaller and younger so I don't anticipate getting to small. I've decided that I will not wear baggy clothes or have a reduction to make other people feel comfortable around me. I wore baggy shirts when I was younger I will not do it again. If I have health problems then I will consider a reduction but not to make people feel comfortable with my size.

Also on the subject of people thinking that you are fat when you have big boobs. I've experienced that when I was younger. My mother in law worked at a shirt factory and had bought some shirts for her daughter. She turned to me and said that she would have gotten me some but they did not have my size. I asked her what sizes she had gotten for her daughter she said a 10. I told her that was what I wore. Her daughter is very broad in the chest area. She was surprised that my shirt size was so small. That is one reason I will not wear baggy clothes again.

Haha, why do some women not like having big boobs? I wear a G or GG cup, and let me tell you, it's an absolute pain. Shirts never fit well, my shoulders and back hurt, there's dents in my skin from my bras, they're not attractive at all. More mass = more sagging. Unless you have implants, larger breasts are not perky. I can't wait to go down in sizes everywhere, boobs included.
