A Wedding Dilemma of Another Sort

OK, friends, I need your help with this one.  First of all,quick rundown of the situation.  Mr Trail Mix and I are attending a wedding in September on Cape Cod and the reception is going to be in a tent.  Since I was on such a dress-buying binge before my own wedding this past June, I made myself promise not to buy a new dress for the rest of the year (I have quite the dress collection, I totally admit.)

Shoes, however, are a whooooole 'nother ballgame.  Yesterday, I went to consign some clothing (which is a great way to streamline your closet and make a few bucks! Peeps in the Northeast, check out Second Time Around, which has branches all over New England, New York and DC, it's my favorite!)

Anyways, while I was dropping of my clothes, I noticed a certain pair of shoes.  They happened to be wedges, which would be perfect for an outdoor wedding.  Oh yeah, and they were Jimmy Choo (I'm a label-whore, I totally admit it!)

So there they were, this beautiful pair of wedge Jimmys that happened to be in my size and that happened to be on sale...You know where this story is going.  Of course, I bought the dang shoes...

Squeeeeeeal!!! Aren't they divine?

So so so SO pretty, right? And since it was a consignment shop, this was technically recycling.  So (through my twisted logic) by purchasing them, not only was I improving my wardrobe but helping the environment.  Winner, winner, chicken dinner!

Alright, so you're probably wondering what my freakin' question is by now, right? 

Here's the deal: I was planning on wearing them with a dark blue dress.  Perfect for a fall wedding, doncha think? But this morning (after I bought them and they're non-returnable) I realized with a sinking heart that back in July the bride had told me that the wedding colors are...Yup, you guessed it, navy and orange. Oh, crap.

So here's my conundrum: Is it weird to wear an outfit that coordinates with the wedding colors? 

I swear it was completely unintentional, I just got so excited by the idea of this beautiful pair of shoes that were miraculously in my size for such a good price! My dress is more of a royal blue, not navy, but still...Ergh.

Weigh in on this one, folks, what do you think? Will anyone notice? Will anyone (like the bride) care? Should I swap the dress for another? I'm reluctant to do this because I haven't worn the dress yet either. Tell me your opinion before I commit some major wedding faux pas!
