My T wears a lot of black and grey. She often will wear an all black/grey outfit and then throw on a coloured scarf as if that somehow makes the outfit better. It's kind of amusing to me. Occasionally she will wear something with a bit more colour but I can only thing of three items of clothing that are coloured. Some of the other therapists at the practice I go to are more "fashionable" I guess but they too don't wear a lot of colour. I think it is just to keep the attention off them.
