The pattern from the April 2013 PRIMA Magazine issue is still available to order by phone until the end of this month.
The pattern is for a Classic Tea Dress. A simple-to-make semi-fitted A-line dress has waist darts for a flattering fit, a scoop neckline, above-elbow-length sleeves and fastens with a centre back zip. Sizes 10 - 20 (UK).
