Nights Out rarely live up to the hype or the expense...
I have to say I often look around and wonder why people are so obsessed with "Nights Out" because they are generally crowded, expensive and crap, ending in hangovers...
Your new clothes will be far far far more long lasting and give you more pleasure - if you do feel really bad invite "the girls" round to yours for a cheap night in to make up for not going out
