Fashion is an issue for most churches since people are inclined to abuse the privilege of a non-uniformed environment and so some of these churches have taken very extreme steps.
For instance if you happened on these congregation and that you are dressed as you are on your way to a club you’d be ushered out.
Modesty is the watchword. They believe that in the event that you feel uncomfortable in a short outfit then it implies you shouldn’t be sporting it, they also believe that miniskirts dresses etc., can be very distracting.
Another disclosure if noise, aside from dancing and singing that of cause is inspired by the choir, distracting and unnecessary noise especially from your jewelries is frowned upon.
