Help my choose a fingerprint charm shape

[mossycat]

I'm having my DD fingerprint charm done next week but I can't decide what shape charm to have. It will hang on a necklace.

Heart shape is cute - but is this a bit dated/ naff?
Oval, tear drop or circle - wondering if these are a more classic shape to wear but are these too boring?

What are your thoughts?

I personally would find the heart a little naff but that's me, if you like it, you should have it. I myself would choose the oval shape. I think it would be more classic than the others.

I think I'd go for oval as I think it would "fit" better with the print than the circle, and I tend to avoid anything pointy on charms, so the teardrop would be out.

By no means a style mecca here, though!

I'd go for the circle, just because. Although the logic that the print would "fit" an oval better does make sense.
