There's 2 that come to my mind.
1st one is Mandy from Artarmon88. Mostly because she is lean and has a 6 pack.
2nd one is Aikko at PrettyBaby Newtown (aka Ayumi @ Summerville Pyrmont) has a cute outie kind of thing happening mostly because she has been pregnant before. No stretch marks or anything like that... just has abit of an outie bellybutton.
Good luck on your search champ
