Hmm, flashy stuff usually trips up the signal, but a clean, low‑profile design can still look sharp. Think matte black or deep navy fabric with RFID‑shielded panels, and maybe a subtle pin that doubles as a discreet antenna. Keep any metal or glass to a minimum and use lightweight, conductive threads so you’re not adding extra interference. If you want a touch of sparkle, laser‑etched crystals that don’t reflect RF waves are the way to go. Keep the colors neutral, the seams smooth, and you’ll have style that won’t ruin the sync.
