Charity "ball" that good friends are organising in a naice but trendy hotel.
I'm guessing you don't actually wear ballgowns to balls anymore? 
So I'm 30, size 14, short. Good bits... Er.... Good cleavage I guess. Have long dark hair also.
Ideally sonething I could wear again (ha), that won't break the bank but makes me look fab. (Twice ha)
Any ideas would be most appreciated.. It's in less that 3 weeks so need to get shifting.
