I am Sara Duke, this is what I do and how I do it.
A French seam is when the raw edges are hidden in the seam allowance of a garment. French seams are constructed by doing double the work- half the width of the seam allowance is sewn, then the garments is turned inside out and the other half is sewn. Tidy, durable and a mark of quality. Often found on garments made of sheer fabrics, and mandatory on dress shirts.
Pictured above is a custom piece for a very lovely client under the "I made this for you." -Sara Duke label; silk georgette over jacket for a three piece outfit (pictured below). If custom work is of interest, for an appointment, please contact email@example.com
