We usually provide the service of adding a buckle, in order to make the jumpsuits more difficult to remove by the wearer.
White buckle is ideal for underwear. Its a smaller size buckle and opens by pinching the two sides.
Black buckle is ideal for jumpsuits. Its a little larger than the white and has an extra button in the center that makes the buckle more difficult to open, as both the sides and button need to be pressed the same time.
Kit includes 1 buckle and ribbon needed to sew on garment.
