Feminine Deep Sea Diver tattoo band for around the ankle

This is what a business in United States was looking for in their tattoo design

I would like a design drawn up for a feminine/elegant tattoo band to go around my ankle area. This design will represent my husband as a US Navy Master Diver. Im not really sure as to what would look best, as I have never had a tattoo before.
I was looking for something Sephia or black in color so that it's not too bright and not too light. It can consist of mermaids, the Mark V deep sea diving helmet, Master Diver Navy Insignia, sea turtles, sharks, octopus and whatever else you can think of that is deep sea related. I don't want it to look to masculine. It can also be of tribal design. Those seem to be popular on arm bands. Read more
