Some friends got together and invited me to join them in a colour playshop that Joanne was running. I found knowing what other colours I can try useful and also learned that you dress with as much contrast you have naturally between your skin-tone, hair colour and eye colour, as you do in your clothing.
I think I will be willing to try colours that I have never tried before.
I can recommend this workshop because it can help you get more value out of what you can buy because you know it will look good!
