Here's the shirt I made. I used the dress pattern pictured on the far right.
Then I added layers to it ala J. Crew style (I literally dog earred the pages of the catalog for things I wanted to make). I made 6 inch strips, sewed along the top giving them a ruffle, then sewed them on seam to seam (hindsight, I should have put them on the front before I sewed the two sides together) 3 inches apart. You can't tell in this picture but the shirt in J. Crew actually had slits along the ruffles (sort of like large rectangles) so I cut about 3 strips vertically on each layer in a brick laying pattern.
