that DS1 went to his (yr6) prom in shorts and a shirt he picked up off his bedroom floor, when all the girls' mums had clearly spent hours helping them get ready?
It wasn't a formal do, BBQ and disco. Dresscode said they should wear what they were comfortable in. The girls were in full makeup, fancy hair and evening dress, the boys mostly like my DS.
DS1 shorts were smart ones!!
OTOH, I'm not sure how I'd cope with my 11yo daughter wearing a strapless ballgown - there were a lot of them about.
