OMG! I went to this site out of my curiosity and they have bra size 28DDD/E. Is that even REAL? Or by that size you're considered to have fake boobs? Like how is that possible? And when you have such a small back, doesn't it hurt to have such big boobs? Sorry if I sound so naive, but I haven't heard of anything like 28DDD/E before.
I'm a 30/32G, so yes, totally possible, and not fake! But when I go to Victoria's Secret they try to convince me that I'm a 38DDD

But yes, I agree with others, figleaves.com or a local boutique. In Rhode Island/New Hampshire there is a lovely boutique called Zoe and Company that I go to and they are WONDERFUL. They will find you literally 100 bras in any size. And they keep fitting you until you have the PERFECT bra. It was pricey but absolutely worth it. My clothes fit so much better now! Check out if you have a local boutique like that!
For reference, the bras that I wear most often are Fantasie and Freya. They are awesome.
