I rarely buy anything from Old Navy anymore because I've found that the quality is pretty bad (that's what I've found, I'm not judging you for shopping there). But! I generally think it's pretty safe to buy tank tops and t-shirts there. This is why when I was buying $.99 flip flops the other day to go with a dress I have, I also bought this plain white v-neck t-shirt. Yesterday was the first day I wore it and BAM!
