If you want to make a cute accent on your individual style you can create a pin with your own design or find a ready one. 

I found a company that would definetely complete all requests that you`ll give them - PinSource, here`s link https://www.pinsource.com/custom-lapel-pins/hard-enamel-pins

To get a pin you need only to send them a picture of what do you want and select a type of pin and that`s it!
