T-shirt design for dive instructors on Bonaire

This is what AB Dive was looking for in their t-shirt design

Our Crew AB Dive will get new t-shirts.
We would like to have a cheerful, sunny design, linked to diving, te sun, the ocean and under water creatures.

The colour of the shirt should be blue.
(Not too dark - to warm in the sun), but not to light - you will see all stains very easily.)

The shirt should match the cap (see picture).
Not the same look and feel.

Maybe use a seahorse or an octopus in the design.

I uploaded 2 pictures of the current t-shirts. We'd like to have a totally different idea. but linked to the ocean of course.
Please use the PADI logo, the dive flag and the Green award logo in the design. Read more
