When you need a particular item of clothing, which store do you head to first, and why?

I might have reason to go swimming in a public pool. I have a bathing suit, but I really wanted some shorts of some kind to wear over the bottom half. So I headed to Goodwill. Within 2 minutes I had found exactly what I was looking for, and didn’t even realize that that was what I was looking for. It’s an actual swim suit bottom with a skirt. Perfect fit, perfect color (black.)
Anytime I need something “new” in the way of clothes, I go to Goodwill. They have an almost unlimited variety of almost everything. Much of it is actually very high quality, stuff you won’t find at Walmart or even Penny’s. Much of it doesn’t even look worn, and it’s very inexpensive. Plus my only other option is Walmart, and no thank you. They have almost nothing, but the same, cheap copy of whatever they do have, and anything I buy there lasts for about 3 wears before it falls apart.
Even if I had a Dillard’s or Macy’s option, I would choose Goodwill.

Where do you go?
