There are all sorts of good reasons why people might dress smartly to come to a church - but in the end, God is much more interested in what is going on inside a person than what they look like on the outside.  We think the same way.

Some people like to come 'smartly' dressed,  others prefer to be 'casual'.  Everyone does what feels most comfortable and we are all comfortable with each other.  Come along and see for yourself.
