*in walks a gear-fetish jackal* Well then, there are quite a lot of things that a shark looks good in. The basis is obviously swimwear. Both male or female varieties there of. Tiny underwear is always a plus as well, but I may be a tad biased by all of this as well. I'm mated to a reef shark myself, and wouldn't you know it... sharks look good in ANYTHING. Hehehe.

So, the question of course to ask yourself is such: what do YOU like? Since slutty is what you are willing to depict, it's going to have to be something that is tight, highly suggestive, possibly small and show off very well without actually physically showing anything outright. Lots of options to be sure. Mini skirts, spandex, swimsuits, armor, underwear, cross dressing or not. :D

I suggest having a look see at my gallery, it may spark some ideas for you. :3 I hope this helps!

Maybe half-transluctant body swimm suit?

You have an example of that? I am unawares :o

Maybe something like this, only that on the pic you let it be a more transluctant one ^^; Just an idea.
