The phenomenon of teenage girls and women wearing sleep attire outside the home has become another last post for society's collapse (so many things to be afraid of, so little time). But as the saying goes, "Before you judge another person, walk a mile in their shoes" - or in this case their pyjamas. Shot in Ballyfermot and the Basin Lane Flats in Dublin, Maya Derrington's tough and tender documentary looks at two of the many who are dismissed as caricatures and on the receiving end of diatribes about class, hygiene and, well, bad dress sense.

Choosing teenage pals Lauren Dempsey and Tara Sallinger as her subjects, Derrington observes their daily lives of laughs, squabbles, bravado and rubbing adults up the wrong way. In the beginning 'Pyjama Girls' feels as if it could be a slog, but as we learn about Lauren and Tara's lives and warm to them the film grows in power and becomes more thought-provoking. It's not an apology for any bad behaviour but it is a lament for wasted potential, a snapshot of youth and a celebration of the compassion and stoicism of carers - a nanny and aunty the Irish mammy here in all but name.

While 'Pyjama Girls' would've benefited from interviews with the older women, and the absence of members of Tara's family makes the film seem a little lopsided, it will age well. Hopefully its stars will look back on the experience from a happy place.

However open-minded you are, you won't like everything you see and hear, but in a perfect world everyone would leave the cinema wiser and slower to criticise.
