Okay, so, I’ve been meaning to get a better handle on bra sizes, you know, like, really understand what those letters and numbers mean. So, I decided to dive in and figure it all out.

I started by looking up some info online, just to get a general idea. I found out that the band size is basically the measurement around your ribcage, right under your boobs. Easy enough, I thought. I grabbed a measuring tape and wrapped it around myself. I wrote down the number. Then came the tricky part – the cup size.
From what I read, cup sizes are all about the difference between your band size and your bust size (that’s the measurement around the fullest part of your chest). Each letter represents an inch of difference. So, like, an A cup means there’s a one-inch difference, a B cup means two inches, and so on. It felt a bit like a math problem, but I was determined to crack the code.
I measured my bust and wrote that number down too. Then, I did the math – subtracted my band size from my bust size. I ended up with a number, and that number corresponded to a letter. I was feeling pretty accomplished at this point, like I was some kind of bra-sizing expert. But I wanted to go a step further.
I started looking for pictures of different cup sizes. I thought it would be helpful to actually see what each size looked like. I found some charts and images, and it really helped me visualize the differences. It was like, “Oh, so that’s what a C cup looks like!” It was kind of eye-opening, to be honest.
- First, I got all the basic info about band and cup sizes.
- Then, I measured myself, which was a bit awkward, but I managed.
- After that, I did the math to figure out my cup size, felt like a little quiz.
- And finally, I looked at pictures to see the real differences, which was super helpful.
I also learned about something called “sister sizes.” Apparently, if you go up a band size, you should go down a cup size, and vice versa. It’s like a little bra-sizing secret. For example, if you’re a 36C, your sister size down would be 34D. If you are a 32C, your sister size up would be 34B. I played around with this idea, trying to figure out my sister sizes just for fun.

Oh, and I found out that a DDD cup is the same as an F cup in the US. But in the UK, a DDD/F is an E cup! It’s a bit confusing, but it’s good to know if you’re ever buying bras from different places. Also found out that many people ask what A cup breasts look like. A cup breasts are the smallest standard size.
My Key Takeaways
It was a bit of a journey, but I feel like I have a much better understanding of bra sizes now. It’s not just some random letters and numbers anymore. It’s actually a pretty logical system, once you get the hang of it. And seeing the pictures really helped me put it all into perspective. I even started looking at my own bras in a whole new light. I feel much more confident about bra shopping now, and I think I’ll be able to find better-fitting bras in the future. All in all, it was a pretty successful experiment, I’d say!
