Classic trench buckle sized for 25 mm sash belts and lightweight coat straps. The smooth, low‑profile frame helps fabric pass through cleanly for fast adjustments at the waist or cuff. Use it to replace worn hardware on a favourite coat, modernize an older piece, or design a new belt for dresses and shirtdresses. The versatile black finish coordinates with buttons and snaps in a wide range of colours and textures for a cohesive look.
