banana boats and sea horses

i'm thinking of dying a top, either bleaching it, or tie-dyeing it. i absolutley L O V E tie-dye, dip dye, and bleaching effects! it looks amazing on clothes, shorts especially! it looks lovely on t-shirts too!
i am thinking of making this design on a shirt:

i know it will be impossible, but i am willing to try! if it goes wrong, it will be okay because any tie-dye looks good!

i really want any of these dip-dyes shorts!;

they are all absolutley gorgeous! i'm thinking of trying to dip-dye the last one, just above^.
i know that you have to get the right dye, and do something with it, i'm just not sure what.
if anyone knows how to, send me a message/comment below?
