What do the free-spirited '60s, temporary yin-yang tatted '90s, and fashion week runways of 2019 all have in common? Two words, one hyphen (and looks pretty groovy on a T-shirt): tie-dye. The colorfully patterned technique has made its style mark over several decades, and we're currently living for its most recent resurgence . We not only love the nostalgic technique for making us feel like carefree camp-kids again but also because it's an easy and affordable trend to DIY on just about anything. To prove it, we rounded up the best tie-dye kits with matching what-to-dye buys that Amazon has to offer and consulted an expert on beginner-technique advice. Shabd Simon-Alexander, designer, activist, educator, and author of Tie-Dye: Dye It, Wear It, Share It, shared just how easy it is to do at home.
