In addition to the operational uniform, we also know the dress suit.
This outfit is worn during official moment, such as a swearing, funerals and so on..
The dressy outfit is based on the former daily uniform. As a result, everyone in the past had access to the dress kit, because it was possible to make a dress suit with a few minor adjustments to a daily uniform.
With the arrival of the operational uniform, police officers who entered service after 2016 no longer have a daily uniform. A dressed outfit can be given on loan for the above-mentioned moment. That is quite a logistical challenge, which means that it is becoming less common for the dressy outfit to be worn on a large scale.
