Here is my summer top -- Butterick 3383 in blue cotton gauze. I think I must have chosen too large a size, because the neckline ended up having a Flashdance off-the-shoulder effect. I solved this by pleating across the front at 2 cm intervals, roughly collarbone to collarbone. The effect is like a peasant blouse, and a little shapelier than the original. I think this will be a cool and pleasant top for summer, and good under jackets in the fall.
The pattern was very easy, and very fast, too. I will make it again -- using a smaller size.
