What to do when you are between sizes?

[mornnen]

Hi Everybody-

I need some sizing advice. I am knitting the pattern seen in the photo here. According to the pattern, my bust is a size medium but my hips are a size large. Go figure.

Here is my dilemma--do I knit for my hip size or bust size? I am hesitant to knit for my hip size because then it would be 6" more than my bust size. But if I don't knit the large, I am worried that the ribbing (which I know is stretchy) would look like it is stretching too much.

The only other thing I can think of is that K2P2 ribbing is often knit (unintentionally) at looser gauge than stockinette stitch and as a result people often go down a needle size or two to tighten it up. So maybe if I knit in the stated needle size it'll be ok?

Can anyone give me some good advice on this? I could really use some help.

Thanks!
