Coachella from the latest issue of Knitty. The only wearables I've made faster are hats and a thong. Less than 2 days of knitting. It took just over 3 balls of Alchemy Synchronicity in Pewter, a single ply silk/merino blend. It's about the only handknit thing I have that I consider hot enough for going out. I'm a 34" bust but made the smallest size. I think this made the drape less than many others, but you have to watch out that the armholes don't get too tight in the front doing this.
If you want to read about the making, you can at the Coachella KAL page here under the evening Coachella post:http://coachellakal.blogspot.com/
