Yeah, I am generally dubious about suits I've found thrifting, although admittedly I've only ever bought one suit non-thrift, so I don't really know what I'm doing either way! Skirts and dresses really depends - I tend to have better luck thrifting with those too, but then I'm almost always looking for dresses with sleeves, and skirts below-the-knee and WITH POCKETS, and good luck finding that ANYWHERE.
