Make your own pair of no-sew Flare Jeans! @orlyshani shows you how to create the classic look with little more than an old pair of jeans, some denim fabric and fabric glue! Pair them with a cute pair of wedges and you're good to go!
While there isn't a tutorial on Bel Rossa, she suggests cutting your denim into strips and then sewing them one-by-one onto a fabric backing, working in layers. I imagine after that all you would need to do is stretch your creation onto a canvas and--voila! Whether you take a stacked or sunburst approach, the effect is pretty neat!
