Decide on one bright color to use to accessorise whatever you are wearing. Many people choose to combine red with black and white, but you can also go with even brighter colours such yellow, green, pink or any other truly african combinations.
The rest of your accessories such as handbags and shoes and jewelry should include the accessory colour you have chosen. They do not have to be exact matches, or the exact shade, but they should be related enough that they compliment each other.
With regards to make up: Try to tone it down there. For example, bright yellow accessories are highly fashionable, but bright yellow accessories with matching eye shadow might be a just a little bit too much.
