You don't like Mera, or just had an inspired female Aquaman design?
I just like the Aquaman colours and it's an easy to assemble costume. I also like taking a male costume and doing the whole 'turning it into a female' thing
The first time I wore it in March I just went for basic Orange t-shirt, green tights, green shoes, black skirt, Long green gloves, DIY Aquaman belt and a blonde wig. I bought a Devil's Trident from the shops during Halloween and spray painted it gold.
I'm working on the costume each time to make improvements. At the moment I am working out how to sew Orange, flat, round sequins onto the t-shirt to give it the scaly look.
