So I am lost on what kind of shoes to wear!! I am having an outdoor wedding in April in TX. Should I wear cute brown boots or blue shoes? Or does anyone have any better ideas? I need to get this taken care of because I need to get my dress altered and they can not do it without me wearing the right shoes!!

So yes, I am starting to freak out a little about this!

Please help!!

I really want the boots, because we have a joke about boots.

I have been riding horses forever and he laughs at my boots. Since I ride english, I have a pair of tall boots and he laughs and says they are hooker boots (even though they aren't, but he likes to really poke fun at me over my riding outfit :).

SO I thought it would be cute if I got a pair of boots, preferably brown to match my wedding colors. I would wear my riding boots, but they are flat and I need some sort of heel since my fiancee is 6'6 and I am 5'4. :)

On the other hand, if I can't come up with some good ideas for boots then blue shoes it is! 

EITHER way, I need help!
