Totally agree with this post. I'm a natural 34DD, with a small frame, and need a large or an extra large to fit perfectly in the breasts, but then it's WAY WAY too big elsewhere - like gaping under the arms, goofy looking through the shoulders, etc. So I usually wear knit shirts in a dark color in medium, so they fit my frame, and don't bag, and the stretching isn't that noticable.
I also wear a lot of camisoles (JJill has really nice ones in many colors) underneath unbuttoned button-up shirts. Unfortunately, I still show a lot of cleavage - almost impossible to avoid unless I wear a crewneck or turtleneck, and then I wind up with uni-breast - and get a lot of negative comments about implants or being sl*tty
I so agree about getting measured properly. I went for years wearing an ill-fitting 36C, and it turned out I had to lower the band number and up the cup. They look so much fresher and perkier in the right bra, and I like them a lot more.
Though it still hurts to see large breasts referred to as udders, or matronly, or slovenly. Elle had a particularly offensive piece on it recently - the only way this woman could love her small breasts was by endlessly bashing large ones, apparently
When looking at other women, I think I'm most draw to a large A/small B, but beautiful breasts can come in all shapes and sizes.
