I can see the appeal—iridescence can throw off a shooter’s eye, but it also gives away movement and position. On a plain backdrop it might work as a decoy, but in a real engagement it’s more trouble than it’s worth. Stick with matte, low‑reflective fabrics unless you’re doing a staged shoot and can control lighting. If you’re going to risk it, treat it like a tactical decoy and keep the rest of your gear as dark and subdued.

For a low‑reflective, dark look you’ll want something like a matte cotton‑blend or a wool‑silk mix in deep charcoal or navy. Think of fabrics that have a slight texture—linen or tweed in a darker shade works too. They’re still fashion‑forward because the cut can be sharp, but the finish keeps you from catching stray light. For a midnight pop‑up shoot, use a controlled light source: a single spotlight or a small LED panel with a soft‑box filter. Keep the background matte black and make sure any accessories are in non‑glossy materials. That way the clothing can be a subtle statement without becoming a flare‑up for the cameras.
