I realise that all themed parties have an element of this. But we are going to a party soon where it specifically says on the invite "long" evening dress for the ladies. I don't own any long dresses, largely because I am a short arse and I don't really do them justice (also I have great legs and if I'm wearing a dress I generally like to reveal some of them!) I have plenty of perfectly adequate dresses that would do the job in terms of being glamorous and sexy and WOW. But no, it has to be a long dress. This means that I'm going to have to go out and buy a dress specifically for this event that I know I will never wear again.
I can understand that the hosts want to set the tone for the evening. The tone is glitz and glamour. I can pull that off without wearing a long dress and begrudge being told the length of my hem.
Grrrr.
