may-smock to wear out!

The theme for the month of may is to make a "smock to wear out!" Another purely selfish theme here. I have tried and failed to make a smock like the one on the right to wear over jeans and and a t-shirt and need to master this look very soon. I think it is so very cool and have to have a smock I can wear out. Patterns are hard to come by for this style, especially for a more modern look like this. I have a ton of vintage patterns, but they are so. . .shapely. But this runs the risk of looking like a big sack. hump. So, I think I am up for the challenge, I hope you are too!
