What color top should I wear under a navy blue silk tunic Overshirt?

The tunic is one that Morrissey has a wide belt around size and has a hook and eye fasting in front of the neck and another at the waist. So the party chest is open, so I need to wear something underneath. His work for a Christmas party and I thought to wear with black pants and heels.

dunno
