The magic of shopping second-hand is that you don't find the right clothes, the right clothes find you. You know they've already been loved, and you're going to love them a little more. You form a bond with second-hand clothing because it feels like new, and you scored. Not only that, but you find classics, vintage, modern, favourites, something for you something for her, something for him. It's sustainable, it's smart and it's clean.
Remember, if you can't stop thinking about it, buy it. You're giving the item of clothing (and yourself) another chance to shine.
