The I Do decorated shoes are Jimmy Choo's. They aren't exactly budget-friendly, but you could do that on any wedding high heels. The aqua sandals with the rosettes are by Nine West. At a fraction of the cost, that's much more budget-friendly!
The bridesmaid dresses are all by Watters.
I think the DIY sugar crystal chandlier from Once Wed is fantastic. (I wanted to call it sweet, but I caught myself.)
The other pictures were found at The Bride's Cafe.
I think this could be a really versatile theme. It'd be great for warm weather, but I actually think it could be a nice winter theme, too.
