I've just ordered a bunch of sweat bands (like USD1 each) for occasions where i need to protect my love bracelet. They are just one tone microfibre material. I mean for times where i need to cover the bracelet (when it's not appropriate to flash gold) and still want to look not casual, I'd probably wrap a Hermes twilly over it.
When your bracelet was spanking new, how much do you wear the sweat band? Please don't laugh at me as i intend to even wear the sweat band when i sleep. Well, i guess until the bracelet hits her first scratch lol.
I am a born left-handed and right handed trained. So i'd say i use both hands 50/50. I still chose to be wearing my bracelet on my left, ie dominant, because i dislike the knocks when i use computer mouse.
