Although there is no right answer when it comes to performing a tummy tuck the belly button is by far the most important cosmetic feature. If the belly button looks natural then the whole abdominal area will look good. If the belly button does not look natural then it does not matter what the rest of the abdomen looks like because it will have to be hidden to cover up the belly button.
When I perform a tummy tuck, I pay close attention to crafting a belly button which is youthful and natural looking. If the belly button looks good, wearing a bikini is a possibility as are low cut jeans etc.
In this example I have worked to create the most natural appearance possible for the belly button which in turn compliments the rest of the tummy creating a natural look which will allow for freedom to wear a bikini or any other article of clothing which may require exposure of the midriff.
