The September 2013 PRIMA Magazine pattern is still available to order by phone until the end of this month.
The pattern for September is a stylish shift dress. The three-quarter-sleeve shift dress has tucks at one side seam to create flattering draping, and fastens with a centre-back zip. Sizes 10 - 20 (UK).
