Haha, it's ok if it has pinstripes and is slightly adorned...
But I can empathize with having to find the size 2 petite stuff. It's a pain...
Business attire is most definitely a suit, even for a girl. I would say if you look nice, though, it's ok if it's not extremely conservative. Suits don't have to be completely black. Usually juniors sections in department stores have cute suits, and ditto with stores like New York & Co. If you're not on a budget, Bebe is good. You just have to make sure it's conservative in a sense that it's not provocative...because I am really surprised at some of the stuff that passes for "business attire" and yet is a really low cut shirt and/or the slit up the skirt is to my crotch
