There will definitely be the right weather to wear this dress in the mid-west - both Spring and late Summer nights. I also found wearing white jeggings with this dress makes it more do-able for early Spring and allows me more time to not worry about shaving my legs ;) - woot! (not sure why I didn't take pics with the jeggings).
There are so many ways to style it, including belted, or not - and with long necklaces. I found it looks great with both heels and flip-flops. I definitely see this being a go-to dress, especially on our beach vacations and to casual spring/summer parties.
