Fashion Challenged

Those of you who know me know that I'm fashion challenged. I recently bought a dress (at TJ Maxx thank you very much) for the much anticipated trip to NYC.
The problem? The dress (a fetching sweater dress in peacock (really? peacock?) by BCBGMaxAzria (any relation of Hank? I love Hank! Oh wait, that's different. Never mind.) the price tag said $240 (really? $240? did anyone pay that much for one?) ) is peacock, a beautiful blue.
Here's my question: what color tights do I wear? Black? I was watching that terrible Dateline Going for the Gold and this woman (the interviewer) was wearing a white dress with brown tights and I thought, will that be me? Will I look that bad? And the problem is, I would. I would look that bad. And not know.
Save me from my fashion challenged fate.
Oh. And I was thinking of wearing my new black boots? Yes? This will be okay?
And while you're at it, could you buy me a new coat? (one to wear with dresses. Yes, that's right, I don't have one). Because I'm fashion challenged.
