What do you think of triangle-bikini on flat chested girls?

I have a triangle-bikini but I'm a bit self conscious to wear it because I'll be with my friends. I'm an a-cup - not completely flat-chested. Do you think it's okay to wear it? I'm planning on wearing a cami over it though, but just in case I want to swim without the cami. What do you think of triangle-bikini tops on a-cup/flat chested girls?
