From Rosie & Me:
The Elise has a French dart (starts from the side, just below the waistline) and a center back seam which are ideal for fitting purposes. The rounded neckline is finished with a shawl collar. The center front has a subtle squared overlay which gives the blouse a vintage a-symmetrical button closure.
The collar, cap sleeve or cuff can be made in a contrasting fabric or finished with a delicate piping for extra detail. The pattern comes with two sleeve variations:
Version A Has a fold up cap sleeve.
Version B Has a 3/4 set-in sleeve, with a turned up cuff.
