Chewbacca Yes, the Whitsuntide dresses were kept for best but always worn on a Sunday "to get the value out of it".
The dress from the year before, let out and the hems lengthened became 'playing out clothes'. Then I had a fairly plain dress, white socks and sandals for school.
After the Whit Walk, we either went to the local park for a sticky-bun-and-pop picnic, or to Sunday School if it rained.
There was another parade in May, but only from our school.
The May Queen led it in a bridesmaid's dress and blue velvet cape with a gold crown on her head. She was chosen by class ballot and the same wretched girl was chosen every year as she had long blonde hair. 
She had maida of honour (also in bridesmaid's dresses) and pages and all those not in the Royal Entourage, brought their bikes, doll's prams, bikes and scooters into school where lots of crepe paper was provided in many colours - and we dressed up the wheels and handles.
Some people even had half-hoops arching up and over their bikes or prams to which hundreds of crepe paper flowers had been attached.
All the local Mums, grannnies and other housewives would come out onto the pavement and applaud us as we marched up and down the local streets.
Anyone who wanted, could then come back to school for the Crowning of the May Queen and watch us do country dancing (Black Nag) and dances elaborated plaits round the Maypole.
I wonder why we let these traditions go?
