Tops
Corset
Why: designed to enhance the chest, if there is nothing to bolster then the whole thing becomes redundant.
or
Boob tube
Why: on a girl with breasts it looks cool, on a girl with none it becomes a bandage with nothing to keep it in place.
Halterneck
Why: yes, there are bras designed to wear with these, but little tits work in tandem with the angular cut of this top. They also show off a shoulder which is a sexy substitute to a cleavage.
alternative
Sleeveless top with detailed front panel
Why: frills and froth cover the chest and make up for what is not there.
