It is a sacred garment worn by the priests of the church.
There are fine gathers around the neck, and the fluffy volume comes from these many fine gathers.
Measurements are taken according to the pattern, so they may differ from the actual shoulder width and sleeve length when worn.
Just for your reference.
It's a very beautiful linen fabric with a firm texture.
There was some discoloration at the bottom, which has now been repaired, but it still has a slight yellow tint. It overlaps with the lace, so it's not too noticeable.
It is long, but you can adjust the length by adding tucks under the bust or shortening the lace.
