This pattern comes from Simply Knitting magazine (May 2013) and it is named Paris in the Spring there. It is also named Briar in Ravelry.
This is a very nice cropped sweater and fits like a glove although it requires a lot of seaming. I had a dozen of cute buttons on my stash so added more than the 6 or 7 requested by the pattern. I knitted it with a little more than 4 balls of mercerized cotton “Cheope” by Adriafil in shade 015 and with 3 and 3.25 mm needles.
