Being a suffragette was a risky business, with arrest or institualization a very real threat to politically active suffragettes. Supporting the suffragette movement carried the risk of ostracization from polite society. So how could you support the movement without being overt? The answer was in Suffragette Jewellery, in the colours of the movement.
The jewellery was often quite beautiful in its own right, which meant it could be worn without too much risk. By wearing it, you could recognise another suffragette while she recognised you in return. In this manner, allies of the movement could show their support and possibly recruit new members for the cause. People often think that the suffragettes weren’t subtle, but they were. They worked on several levels, because they were fighting to breach the huge wall created by a patriarchal society.
I’ve mentioned before how jewellery can be used as a metaphor in a narrative. This is another fine example where you can add layer of significance to a character by just adding a few items of jewellery. Your suffragette character can wear her heart on her sleeve, around her neck, on her finger or anywhere else she might like. Your female character can be secretly rebellious, signalling a larger rebellion to come.
