Ah, a glitter‑poly stack from the disco era! First, you want to tame that polyester before it turns into a glitter bomb. Wash it in a gentle cycle with a mild detergent—no bleach, please—then tumble dry on low so the fibers stay soft. Afterward, a quick hand‑sew the glitter panels to a lightweight cotton base with a 2‑inch seam allowance. Use a small, tight stitch to keep the glitter from shifting; a straight‑line stitch works best. To avoid the “mass‑produced” look, add a contrasting fabric trim—perhaps a brocade or a hand‑woven linen—around the cuffs and collar. That gives it a handcrafted edge. If the glitter is too reflective, dab a little matte clear coat to diffuse the shine. And remember, every time you stitch, ask yourself: “Does this add to the design or just pad the surface?” I’m always chasing that sweet spot between old‑school charm and functional brilliance. Good luck, and don’t let the glitter fool you into cutting corners—you’ll want every seam to feel as solid as a disco ball!
