People sometimes use thrifting, vintage and second-hand interchangeably, but to me they're wonderfully different things. Thrifting is the act - it's the rummage, the hunt, the adventure of going out with an open mind and seeing what you find.
Vintage and second-hand, on the other hand, are the items themselves. A piece of vintage is something with a story, often unique in character precisely because of the journey it's been on. That chip on the rim of a teacup, the faded monogram on a linen napkin…that's not wear, that's personality!
