At the neckline for Tempting II

My Tempting II is coming along, but I'm not sure if I like it. I made the sleeves longer, and that went fine. I did the gauge swatch in stockinette, and it was perfect. However, because the yarn is so spongy, I think I knit it too loosely, and it seems too big. Not tight-fitting like the picture in knitty. But I am almost done, so I will finish it anyway and see how it comes out, for the Sexy Knitters Club knit along deadline on August 31.
