Amy, you are getting great shopping advice here already from others more knowledgeable than I, but I just had to pop in to say I LOVE you in these colours; they bring you alive. And I love you for being such a great sport. Also, despite have zero bust, and being at least 5 inches shorter than you (I think) I have experienced BOTH these issues. For the cleavage (or bony chest, in my case) a camisole or tank has solved the problem. I just get into a little summer layering. For the length, I don't know what to say. I do not understand these manufacturers!!

I love that blue on you! Too bad #4 won't work.

I don't know if this suggestion will appeal to you, but I found several great dresses at Kohls recently. It might be worth checking out.

Amy, you are SO right in your assessment of most of the frocks out there this season. It's a really bad and disappointing assortment. The longer and more wearable work options are available - but you just have to look harder for them. Kari has sorted you out nicely

I echo what the ladies have said. The colours in the dresses that you chose are GORGEOUS on you! Too bad they weren't completely right.

I actually really like the blue one on you. Maybe it's because I'm Spanish and we have a different culture, or maybe it's because I'm well endowed and therefore used to worse cleavages than yours, but I see nothing wrong with those necklines. You may add a cami if all else fails (done that with seriously low necklines before)
