Thoughts on a new bustle dress

Michael and I have a picnic coming up toward the end of the month and I was thinking of trying to through something together using parts of a dress I already have and just making modifications, ie less sewing ;)

Since the picnic is in summer and at a lighthouse I want to go with a blue and white theme using these fabrics 

And utilizing the skirt and train from this dress I made last summer.

Here are some of the fashion plates I am looking at for inspiration:

Comments and suggestions are totally welcome btw :)
