Thar she grows!

I'm finally swatching, and things are going well. The unwashed swatch was dead on for the row count, but I had way too many stitches width-wise. Then I washed it, it's blocking upstairs -- and so much wider than it started out! Will re-measure once it's dry, but I think I'll be spot on (or close enough) for gauge. Bamboo really does bloom like you wouldn't believe.

One question, though: my bust is 33 1/2", the XS is 33 3/4. Should I be worried? After everyone's sizing issues, I'm a bit concerned.
