Hi All, I know I've been largely absent lately, due to being overwhelmed at work, so I hope you don't mind my asking for some help. I need an outfit to wear to an event where I will be receiving an honor along with some other scientists. It's rather a big deal, so I'm nervous about coming up with something to wear. The occasion will be in the evening in April in DC, and the dress code is "business".

To make things simple, I thought I would just wear a dress and pumps. But I'm having a terrible time finding a dress. The parameters are:
-can't be too short
-can't be bodycon
-a bit conservative is probably most appropriate, so nothing too out there

I am rectangular, short-waisted, short-necked, short, busty, so:
-no boat necks, slit necks, or cap sleeves

I don't like "sweet", so A-line is not really "me".

I've tried this Kamalakulture (too body con) and this Adrianna Papell (the ruching around my mid-section "thickens" me in a way that is not that flattering, although it could work if I lose the 4 pounds I've gained this winter). I was wondering about this Ann Klein or this Michael Kors (in regular sizing, they would probably hit me just above the knee). Any suggestions for places to look or styles to try? I've already perused Nordstrom's, Ann Taylor, Zappos, and Anthro. Thanks very much...
