Everyone I meet knows at least one large busted woman who would look fabulous in a Campbell & Kate shirt. But how to tell her?
Discretely.
First, it depends on who you are. If you're a woman, the sky is almost the limit--especially if you're the genuinely caring type who has even a smidgeon of charm. If you're a man, it may not matter how caring or charming you are. There are some women with large busts to whom you can never speak directly about Campbell & Kate.

That's because it also depends on who she is. If she's your best friend, sister, mother, or girlfriend, then whatever your gender, you can easily tell her about a classic white shirt made just for D cups and up. If she's a co-worker, you should probably be a woman who knows her pretty well.
However, no matter how well-intentioned you are, some women aren't going to be very receptive to the news, even from another woman. I learned this last month when I sat mesmerized during this speaker's talk about niche marketing.It wasn't her material that held me rapt, but her full bust atop her slender torso. I was determined to beat everyone to the front ot the line to speak to her after her presentation. Unfortunately, I was so premature in my sprint to the front that she thought I had a question for the Q&A session.
"Yes?" she called to me.
