Without exception, every single girl dressed for a prom, ball, formal or leavers dance I’ve seen this year - and I’ve got friends on FB with teens across the UK, Ireland, NZ, OZ and the US - all of them have worn longe sleeveless dresses like the green one posted by the OP.
I haven’t seen a single girl dressed in anything remotely comparable to the dress in the OP.
I don’t get why the OP has started the thread, because frankly who cares what people are buying and selling on FB, and the OP’s daughter certainly doesn’t have to wear it.
But trying to make out that girls wearing floor length dresses to end of year dances is ‘frumpy’, is ridiculous.
