I'm with Pels...flat caps and straw boaters to a wedding?...a bit cazh, wouldn't you say?

I think the boaters were gone by the end of the war. They were very popular in the late 1890s and early 1900s. They were mostly made in Luton because the fields in Bedfordshire produced the best straw. Straw-plaiting was a huge industry in Bedfordshire...men, women and children practiced it. No special equipment was required and a woman could plait a line of straw while walking down the street.
So the boaters that are still being produced likely come fom somewhere around Luton.
