Trivial Fashion Question of the Day: Which of these bridesmaid dresses should I choose?

I was asked to be a bridesmaid in a friend’s wedding in May. She picked out the color champagne for the dresses, but is allowing us to choose our own style. I haven’t been able to find a single thing in a store, so it appears I’ll have to order something from online.

I’ve chosen to order from a company through Amazon called CocoMelody even though the $30 shipping cost is outrageous, simply because you can’t beat the fantastic reviews. I’m trying to choose between these two dresses:

One and Two

Yeah, yeah, I know they’re very similar, both being knee-length strapless corset dresses. Both have great reviews as well. It’s a rustic-theme wedding, so we’ll be wearing cowgirl boots (that I have yet to purchase). So, I’m wondering which of these dresses would probably look best with the boots. They both have the corset tie-up back with a side zipper that many have had issues with, but is easily fixed/replaceable. The obnoxious flower is detachable on both.

For reference, I’m about 5’5” and 135 lbs. I’m ordering a medium and will take it in if I need to.

So, let’s take a vote: one or two?
