My mum and Dad's ruby wedding party is in a month's time and I'd really like something in a kingfisher blue colour but I'm struggling. I'm 5'9, size 8-10, no norks, legs not too bad. It's a daytime party so not too OTT but want to make it look as though I've mad an effort! Oh and budget will stretch to £150 if it's the right thing. Please, please help.
