I made a size large with no alterations. It's only two pieces; the body and the front band. In such a sheer fabric and such odd-shaped pieces, it would be easy to get lost in the puzzle, so I cut it out using additional notches where there were circles or dots. This worked out great; it came together so easily.
Since the fabric was so sheer, I opted not to serge it. Instead I zig-zagged the seam allowances and then trimmed. For the hem I just turned and stitched.
This is such a great little jacket and such a quick sew, too. I may have to make another. Maybe one for my daughter--I have enough fabric leftover as Fabric Mart sent so much extra.
Till later; Happy sewing all!
