Seeking silent bangles

For the first time in ages I'm wearing a black top, and black shoes. To avoid looking like a guest at a funeral I added a pop of colour. The trousers. They are too big so I can wear another pair of trousers underneath in winter. Today I just had to pull them up all the time. A new feeling to me!

A close-up:



Normally I would wear a few bangles but I'm in a classroom with more than 30 other students, all working on our computers. My wooden bangles would be too noisy so I have to find some that are completely silent. Any suggestions? I hate wearing tight fitting bracelets and watches, so what else is there?
