Normally an IWB guy but am wearing a suit at this event that restricts IWB ability

I’d like an OWB holster that keeps the pistol tucked nicely against my torso and doesn’t ride down too low. Will be covered by my jacket but I don’t want it protruding too badly so a bulky holster is not ideal

Can be a leather or a kydex holster, no preference there but I would appreciate rationale for one over the other

Thanks
