Here is a collection of patterns that I think would be a good fit for your badass brand. They are quirky, creepy, cute and some of them are seasonal but most would work all year round if you're "that kind of person". Some of them might be more suited for the "girls" section as they might be too cute. As I have mentioned before, I'd be happy to adjust colors for you.
Please have a look and get back to me!
Addendum: Now updated with patterns that somehow belong to the TROPICAL realm. Enjoy!
