The fishtail plait was a hairstyle I am familiar with since being demonstrated how to create it in first year, the striking pattern always looked amazing in photos, and people who have thick hair like my model would make it look glamourous. 

 

I also thought of the idea of her hair being tied up in a fishtail bun, rather than just a fishtail plait.

 

Another idea of hair being left down natural, sprung to mind. My models hair is naturally long and has a lovely thickness, so I thought perhaps if i plaited it , and took it out during the shoot, it would create some kinks in the hair.
