I'm not giving up on the Bombshell. I measured myself tonight, after reading Chickn's comment on my last post. I think she hit the nail on the head, or at least, one of the nails. I am smaller than I thought, for one. The other problem here is the yarn. Sandy, at Purlescence pointed out when I bought the yarn that the sample she knit was sized for the mannequin in the store, but she can wear it. This yarn is major stretchy. The size I was knitting, it turns out, is only 1" smaller at the bust than my bust, not 2". Also, the waist of the size I was knitting is actually too big, and it's ribbed, so that can't be good. I am very tempted to knit the smallest size, which would make the bust 5" smaller than my bust and the waist 3" smaller, but ribbed and with a stretchy yarn that somehow seems like a non-issue.
Either I am a glutton for punishment or I really like this pattern. Or both.
