It's impossible isn't it? I've got a 40th to go to and the theme is 1977 (see what they did there). There will be a lot of old school friends there and I want to look good and ideally not like an ABBA tribute act - any suggestions? It's cocktails and dancing rather than a dinner so a party dress would be what I would normally go for. I'm 5'8, size 10 and a pear (SUCH HUGE THIGHS) so the jumpsuit look - which I really like - just doesn't really work on me :(
