Simple black rubber bangle.
This style is perfect by itself but also layers wonderfully.
Rubber bangles are the best! comfortable, edgy looking, soft and silent...no clunky noise.
To work out the correct size bracelet:
Make a fist of the hand the bangle is to be worn on and measure the length from the outside of the first knuckle to the point between the third and fourth knuckle.
This measurement equals the required diameter of your bangle.
for example, if the measurement comes to 6.5cm, then a 6.5cm (inside diameter) bangle should fit your hand.
small 6 cm / 2.4 inches
medium 6.5cm cm × 2.6 in
large 7 cm / 2.8 in
