It's cute an all, but it's virtually identical to two of Teva's patterns from her book Loop-D-Loop. If you cross the Ballet TShirt with the Steek shirt, you get exactly the same thing. I've knit both patterns. You can see pictures of the various shirts here.
And Grumperina's tivoli/picovoli and several other patterns use the same raglan cast on and shaping. It's a basic pattern - what makes all of the variations unique is the combinations. I'm making one now based on tivoli, with a lacy inset like Green Gables and the lower 6 inches is the lace pattern from Lelah. I may try one like this one, one of these days (or years).
