Wardrobe Oxygen just did a post on this that might be helpful:

Cup size is relative to band size so saying you're an X cup really says nothing about overall volume - Angie, you and I are both D cups but I'm pretty sure you're a lot smaller than me.

Thanks for posting this! I was just asking about wireless bra for 32D on my own thread. This is really helpful.

I reached a point in quarantine when I just couldn't stand the wires anymore, and ordered a few different styles from Macy's (good selection online).I don't know that I am particularly short-waisted, but the underwire seems to jab my stomach. I am a 38 DDD/G, and I was looking for something with considerable support. Glamorise did the trick. They look good under clothes and don't smush me (no uniboob). They also make sports bras if you are interested. They weren't expensive on sale, and you can find a great range of bigger sizes.Um, if you're looking for a PRETTY bra, these probably aren't it.

I don’t wear bras at home, but appreciate hearing everyone’s ideas for when I one day will be back in the real world again. In the meantime, the only thing I have to offer you are this joke about losing weight, and a photo commentary on how well it describes me, lol. A guy I sent them to claimed not to see the humor; perhaps YLF is a better audience for them.
