This accessory dress from McCall's and 1957 is versatile and lovely - a dress you can dress up for parties or down for every day.
Here is the scrap that was tucked in the pattern envelope, a beautiful shimmering blue, (alas, the shimmering aspect doesn't come across in this scan).
From the notes the seamstress wrote on the envelope, she planned to sew view D in a black silky plaid, with detachable blue taffeta collar and cuffs. Can you picture it? :)
