I very rarely go on nights out, and living in a small town can get away with pretty casual outfits for a night out when I do.
I have been invited to a hen night in the city and have pretty much no clue where to start as to whats in fashion for nights out in the city, and which websites are best to look at.
I've had an unsucessful shopping trip, and need some direction please.
I'm in my early 30's, 5'10", average build, and not got a lot of money. 
Any help would be much appreciated.
