Lets see.........how to say this without being thrown off........
as you're a lady, not around the belly button. Looks good now, but what if something breaks,

, and the belly grows for 9 months, not real sexy then, and, it may never get back to normal....
ankle is ok, but, just ok.
upper body, slightly below the bra line could be good.
lower front, below the bikini line is a nice place as well, as long as there is space cleared for it.
on one of the rear cheeks, or, at the beltline in the back.
favorite,???? has to be the below the bikini line........gives a little bit of nasty to it.
just from a guys perspective. (I like the battleship idea, across the chest. i wonder where the guns would go?)
Smile folks. don't take life to seriously.
