Ah yes, the jim-jammers ... they have really come to prominence in the past couple of years. I'm glad to see they have a colony in the West. I thought they may have been a strictly Dublin phenomenon.
There does seem to be an unwritten rule about how far they travel from their home base. You would never see one for example in Dunnes in North Earl Street, but would see plenty in the Cathal Brugha Street Centra, about 150 metres away, or Liam's on Sean Macker. I've noticed at least one near me who wears her most fragrant and fashionably stained jim-jammers to go collect 'deh Phy' in the City Clinic daily.
I'm still trying to work out if the 4pm ones are of the 'early to bed' or 'not arsed getting dressed' variety.
It's a wonderful world.
