Check out this elegant jacket made by Roberta at Treadle.
Roberta used one of the lovely Japanese double gauze fabrics, which gives the garment a lovely drape that works well with the flowing, unstructured style. Because the fabric is double-sided, the inside of this unlined garment has the same print in negative; that plus a tidy seam finish means this closure-free jacket still looks good when the inside shows with the wearer's movement.
The pattern is Vogue 8088, a Marcy Tilton design which has recently been discontinued, though it's currently still available at Marcy's website.
