One signature piece, that is. Take this Vanessa Bruno skirt. It's $195 (originally priced at $560), which is admittedly a lot for a skirt. But it's obviously so well made and, yes, expensive looking that it will instantly elevate anything else you wear with it.
As much as I love finding bargains at Target, there are times I have to remind myself that quality does show. Spending a lot is no guarantee of finding well made clothes, but it certainly improves the odds.
