Shopping online consignment is often a scary gamble (is it clean?, is it damaged?, is it even real?!). I love The RealReal because it takes the guesswork out of shopping secondhand. I completely trust them...and they seem to always have a sale, so how could I complain?
Everything I've ever ordered from them is exactly as described, clean and certified authentic. The only downside is that sometimes the clothes don't fit as expected because they have been stretched by the previous owner, BUT it's a great way to buy designer at a fraction of the price.
