Good point, SweetBody. I think brown or camel-colored clothing would work best. More earthly tones would look very nice. I kind of think of Fall in regards to more earthly colors. You have to think casual with these bangles because I haven't seen bangles as suitable formal wear. Evening wear is possible, but I've seen this mostly for the trendy and fashionable femme's casual daytime clothing. You could probably get away with wearing these bangles with elbow-sleeve clothes. Short sleeves or sleeveless tops would work best with these bangles.
This is an off-topic note. An old JCPenney sale paper I have offered a pack of 50 bangles for sale. So it MAY be possible to have a lot of bangles on your arm. Thing is, 25 would be too many. I'd probably keep the details to a minimum and only show off what you'd like to show off. The bangles should likely compliment a look not BE the look.
