I call this one the "tubed top" it is achieved by putting the body of the shirt on normally but leaving the top part unbuttoned. Then you just take the sleeves and wrap them around the bosoms, creating a bustier type top with flowing bottom. It's very babydoll, which is why I opted for this preppy print to give it some more structure, but I think it would look awesome with stripes or a plain print as well. I may try this on the boat with my linen shirt this weekend.

In terms of difficulty of execution, it's MUCH easier than the one shoulder style - but also much less secure and stable. Most likely best for augmented or smaller breasts, it's still a cool way to create these kind of architectural shirt stylings with something you already have in your closet.
