The current PRIMA Magazine is out - August 2012.
Their latest pattern for ordering is a loose-fitting bandeau jumpsuit, with elasticated waist and no fastenings. Full-length for evenings or short for the beach.
Looks to me to be an easy make for beginners, and shouldn't have to many fit issues - being loose, a knit 'n' all :)!
