I'm going to a smart 40th birthday this weekend - think home counties, big marquee in garden, champagne but also bouncy castle and children's entertainer for the children, all afternoon affair. Only problem is, life has been super hectic and I've not thought about what to wear at all. I need an outfit (probably a dress) and have no idea where to start. I'm feeling pretty rubbish about myself as I've let my weight slide and am now a size 12/14, really self-concious about my tummy. There will be lots of waif like women who are incredibly well dressed there. Budget about £300, maybe a little more for something really beautiful. I want something classy, elegant and easy to wear rather than something fashion-y or hard to pull off. Has anyone seen anything beautiful? Happy to order a few things today and return.
