The pattern from the June 2013 PRIMA Magazine issue is still currently available to order by phone until the end of this month.
The pattern for June is a really pretty chic dress - perfect for weddings, parties and other celebrations - maybe a classy dinner-date too ;) ? The slim-fitting peplum dress has above-the-elbow sleeves, soft-tucks at the front neckline, and fastens with a centre back zip. Sizes 10 - 20 (UK).
I think you could easily use this pattern to make yourself a cute peplum-top too. Also, I think the addition of a waist-stay (perhaps some pre-washed/shrunken soft cotton-tape?) would help to maintain the shape and definition of the waist. For less creasing and easy wearable fabric - how about some double-knit or ponte (with minimal stretch) :) too?
