UNITED STATES – When Amrit Tietz combs through packed flea market fields, she is on the hunt for gems like vintage Levi’s jeans, hard-to-find band T-shirts and fringed leather jackets.

Not for herself – for her three-year-old daughter, whose wardrobe, she estimates, is roughly 70 per cent vintage. “I would rather buy that than a Frozen Elsa costume from Amazon,” said Tietz, 38, who lives in New York City and started collecting children’s vintage even before she became a mother. “It feels more thoughtful.”
