You hear vintage for kids and think faux concert tees (circa 1986). But one too many spin cycles and they look a little washed up.Take a step further back in time with Blu Pony Vintage. The new line takes its inspiration from the ’20s and ’30s, when every piece was made to last — because it had to.Founder Bonnie Matthews uses her collection of vintage Americana kids’ clothing as a starting point and, after copious research, adds historically accurate details and embellishments to create the reproductions. French seams, ruffles, cotton lining, pewter buttons — every item from 100 percent cotton, silk, or wool (no synthetics).Favorites include the Greta Garbo ruffle dress for girls and the cotton denim Albert Einstein coverall for boys, intentionally designed for climbing trees and scaling fences, to be torn, patched up, and handed down. Talk about aging gracefully.Available online at stringbeancompany.com and lilswanky.com, $74-$224.
