T-shirt Design Brief
I am looking for a design that communicates courage and confidence. The slogan I want to use is ”You Ain't Seen Nothing Yet". This sentence is what you would say to a friend who is defying you to do something challenging and you are accepting his dare.
Sample #1
You Ain't Seen Nothing Yet - Hold my Beer
Sample #2
You Ain't Seen Nothing Yet - Hold my Margarita
Sample #3
You Ain't Seen Nothing Yet - Hold my Phone
Sample #4
You Ain't Seen Nothing Yet - Hold my Boots & Horse
Sample #5
You Ain't Seen Nothing Yet - Hold my Camping Equipment
Etc.....
I want one standard design that would be interchangeable among all samples. As you can see, the second sentence “Hold my XXXXXX” it gives you an idea at to whom the person wearing the t-shirt is into. It displays a little bit of his personality, what he likes, what his hobbies might be, etc.
