Do you know of a similar pattern?

My sister-in-law got this tunic for Christmas... http://m.soma.com/store/product/live.-lounge.-wear.-soft-jersey-space-dye-tunic-with-pockets/570157143?color=8427&catId=cat8239311&fromSearch=true&scPos=1-2101-3333 ...and asked if this is something I could replicate. It looks easy enough, if I had a pattern. Do any of you know of a similar tunic/dress pattern? Thank you so much for your help! Charlene
