One star, one word — and everything ignites. The BOOM brooch by Petit Poirier is a soft blast of energy: stitched like a shout, glowing like an idea taking flight. Embroidered in vivid threads, then hand-cut and assembled in France, it’s a tiny explosion you can wear. Pin it to a denim jacket, a crisp shirt or a tote: it tells the story of a moment bursting open.
