The Park Lane dress and top are beautiful floaty garments.
You can choose between a flowing midi dress with delicate waistline gathers, or you can make the elegant darted blouse, both finished with a keyhole opening and a simple button and loop closure at the back neck. There are two different necklines and three sleeve variations to choose from, along with an optional shoulder ruffle. The full-length sleeves feature a button cuff with placket whereas the more voluminous mid and short sleeves finish with a plain band cuff.
Skill level: confident beginner/intermediate.
For the dress: fabrics with plenty of drape such as viscose/rayon, crepe, silk
For the blouse: as for the dress, but it would also work in soft cotton lawn, chambray, double gauze
Both: a small amount of interfacing for the cuffs and neckline; if your fabric is very fine or shifty you may want to also interface the zip area.
