I have been invited to a 40th birthday party this summer that is Bollywood themed. It is going to be a big bash and probably quite glamorous, knowing the hosts. I haven't got a clue what to wear. I haven't got anything in my current wardrobe that would fit the theme at all. I want to buy something that isn't a full on sari because I'd like to be able to wear it again so I'm looking for an evening dress that has a nod to India. Nothing too bright, and I'm a short size 12.
