Yorkshire
In East Yorkshire young folks go to the nearest market-town to buy some small article of dress or personal ornament, to wear for the first time on Easter Sunday, as otherwise they believe that birds—notably rooks or “crakes”—will spoil their clothes.—N. & Q. 4th S. vol. v. p. 595.
In allusion to the custom of wearing new clothes on Easter Day Poor Robin says:
“At Easter let your clothes be new,
Or else be sure you will it rue.”
