littlek...you just brought back a memory of a teach I had in 4th grade.
she was really nice, all the kids loved her.
it was her first teaching job too, and I remember she must have owned like 2 skirts, and 3 shirts at first.
she'd mix and match them as best she could, same shoes every day.
then, after a couple of months, she must have gotten a few paychecks under her belt, and there started a slow trickle of a new blouse here, a new skirt there. In a way, it was really sweet, it was like we were watching her "grow up"
If you just need a stop gap until you've got some money put aside, how about target or (cringe) Walmart.
I don't go to Walmart out of principle, but, I was forced to the other week because they were the only one that carried a specific cleaning product I needed.
While there, I saw these tank tops, like to wear under another shirt, or under a blazer or something, and they were like $5/each. I have to be honest, they were as good a quality as other tank tops I've seen for 30 or 40 bucks. I'll admit it, I bought 4 or 5 in different colors, and I've worn them several times.
