Being creative gets your imagination going. Think about why you want to wear something, and how you are going to wear it. I used to think why do people wear necklaces? It is to add to a look, to enhance a look, to flavour your outfit.
It does not have to fit convention it does not have to be perfect, but it does need some imagination. How you dress is a lot do with some creative imagination. Lately everyone wants to look a little different lately, this is exactly what the world needs right now. Being inventive encourages your confidence. Try and test this little theory. Find a skill in putting random things together and you never know what you will come up with, possibly a bespoke creation to sell, give as a gift, wear or admire. Get some ribbons, pins, flowers, bows, start attaching them to a plain cheap necklace, get playing and see what you come up with.
