Without thinking about the overall plan first, I matched the print across the center front and then just barely had enough to cut out the back along the border edge. To make it work, I left off the gathers at center back and the scallops at the side seams don't come close to matching.
I modified the long sleeve to make it a 3/4 length bell shaped sleeve with a cuff. The cuff was a happy accident - my original mod was too long. The other significant change from the pattern was that I added a full lining. This fabric is a bit coarse and the embroidery adds to that so it wouldn't have felt great against the skin. This was a pretty easy modification to make and it really adds to the wearing enjoyment for my daughter.
The pants are also a linen-look fabric - white, with a black pinstripe (that doesn't want to show up in the photos). I debated about lining these also, for the sake of opacity but decided they were okay enough as is. The fabric isn't very thin. I did use a beige lining fabric for the pocket linings to prevent show through there.
The pattern is Ottobre 3/2012 #38 - a pair of boys' narrow leg trousers. I added quite a bit of width at the hem, but wish that I had added more. I was hoping for a real wide-leg look. Apparently, the original pattern has very narrow legs. I'm happy with the fit otherwise. Deciding on the length did give me pause. I would like them to fit for awhile, but I don't think white pant hems dragging on the ground would be good.
My daughter has gotten so many compliments on this outfit, including women saying they'd like one just like it. It did take longer to make than a dress would have, but it's unique and suits my daughter well. It's a winner!
