Is this a good outfit for a kenny chesney concert?

Well, the images are very small, so it's kind of difficult to tell. Judging by the first one, I'd say no. It's not that the dress isn't cute, but the way the waistline of it bows up in a arch can give the illusion of being pregnant. In the second pic, the arch doesn't seem as pronounced, and it looks much better. I think I'd find a cute belt to throw around it to match the boots. Do that, and you're good to go. :)
