Your kids are an endless supply of good material. Mom, will you marry me when I grow up? But sometimes the best material is the old stuff, like British designer Louise Hedley’s unique garments made from vintage fabrics. Inspired by color and print, NYC-based Hedley crafts simple sundresses and twirl skirts from silk, chiffon, and 1940s cotton bloom fabrics she finds around the city. Bright color combinations make the collection pop. But it’s Hedley’s attention to detail that sets her handmade pieces apart: hidden zippers, delicate satin edging, and rare lace trim are the norm. Best of all, she even takes custom orders. Perfect for your little material girl. Available online at etsy.com.
