I've been trying to focus more on buying quality things over quantity (like holding out for one perfect pair of black pumps and replacing the heel caps after they wear out, instead of burning through three pairs of cheap ones). But every so often, I stumble upon something that's good and cheap, and it feels fantastic.
Old Navy vintage tees. They're soft, have a perfect long and lean cut, and come in a bunch of colors. They even hold up in the wash -- all for $10 (and possibly less in-store: they were only $5 over the Fourth of July week!). A girl always needs a few good tees, right?
