What to knit, what to knit....

I'm fretting over what to knit. I'm working on a baby cardigan for Slimer (the nephew), and I think I want to do something for myself. I have a good amount of a ribbon yarn I like (700 yds or so, maybe more) , and I like the idea of a ribbon tank, like the one from knitty http://knitty.com/ISSUEspring05/PATTxback.html. However, I'm concerned about the back, as I like the whole wearing a bra thing, esp with something with holes in it.

Or I might do something completely different. We'll see. I need to finish that dang cardigan first.
