CDV Showing Sleeve Seam

The dropped sleeve seam of the time period is easy to see in this photograph of a woman in a plaid dress. It looks like there is a small tuck over the sleeve seam as well. This gown features cloak sleeves trimmed with lace at the cuff. It looks like the lady is wearing a snood, thus the flat bow on top of her head. Note the ornate chair with all of the turned wood.
